Originally this film started shooting in 1921, but an accident on the set forced all the previously shot footage to be abandoned and the film entirely reshot on a newly
designed set in 1922. The set comprises of a house interior in which everything had
been mechanized, including the stairs. They consisted of an escalator type stairway
which could be reversed. On the second day of shooting Buster was going up the
escelator when it suddenly gained speed. Before he could jump clear, one of his slap
shoes caught between the steps, jamming him at the top. He yelled for it to be shut
off, but before it could be, there was a sound, mixed in equal parts of a two by four
brace breaking and Busters ankle snapping. The slap shoe tore from his foot, it's
sudden release sending him headlong to the floor ten feet below. He still made a
perfect shoulder roll landing despite his broken ankle, but as he came over onto it he
fainted. It might have put an end to shooting for a while, but during his recovery he
took on another role, husband. He married Natalie Talmadge, the least famous of the Talmadge sisters, Norma and Constance being stars in their own rights. Keaton used
his own house, the 'Italian Villa' for the exterior scenes of the deans house. Keatons
mother, father and sister also appear in the film.

Buster has qualified from collage and we seem him sitting with two other students,
they have also just been presented with their diplomas. The three of them, one girl,
Buster and the 'heavy', are talking. Buster tries to examine the flower in the girl hair
with a magnifying glass and she take exception to it. An argument starts to develope
between the three of them and they all drop their diplomas. They get muddled of
course but no one notices. The Dean asks if there is an electrical engineer amongst
the newly qualified students, who would like to automate his house for him while he
is on vacation. The heavy, who is now an electrical engineer, goes forward and offers
the dean his diploma. The dean looks at it, shakes his head and says he will not do.
The heavy goes back to his seat to find Buster talking to the girl. He pushes Buster
away, and he bumps into the dean. The dean takes Keatons diploma and looks at it.
"You'll do" he says, Buster is suddenly qualified as an electrical engineer. At this
point the real electrician looks at his diploma to find it qualifies him as 'Professor of
Manicure and Beauty Culture'. The girl snatches it from him giving him the one she
picked up. The electrician is now a doctor of 'Botany and Allied Sciences'!

We arrive at the deans house with Buster, the dean and his family. The family is ready
packed for their vacation, and they leave Buster alone to work on the house. Buster
sits on the front steps reading the book, 'Electricity Made Easy'. The picture fades out.
We rejoin as the family comes back from their holiday, the dean is eager to see what
Buster has done. Buster starts to show him round the house. First he shows him the
escelator and then he takes the dean into the library and demonstrates the book selector.
An open faced, book sized box, travels along behind the books, selects the required
one and then delivers it to you on a long pole. Next we go upstairs and see one of the bedrooms. The bath travels out of the en suite bathroom along a track and stops next to
the bed. The bed folds up into the wall at the touch of a button, the doors too open and
shut when a button is pressed. The dean wants to try out the escelator, so he steps on
it, Buster stands at the bottom and works the controls. Suddenly the escelator speeds up
with Buster and the dean on it, sending the dean across the landing, out the window at
the top and out into the swimming pool, Keaton jumped clear just in time. He is
concerned for the dean, and tries running down the ascending escelator, he gives up and
slides down the banisters instead. After he helps the dean out, he demonstrates the pool's rapid emptying and filling abilities controlled with, what appears to be, a railway signal
lever.

We return to the library were Keaton demonstrates the automatic pool table. the balls
go along the floor, up the wall and into a storage rack. When ready for a game, press
a button and the triangle is lowered and the balls run down a shute into it. The dean
asks Buster if he would like a game. Buster, obviously has no idea how to play, but
says yes anyway. He breaks his cue, after fiddling with it for a while, he bends it into
a golf club shape, stands on the table and gets a hole in one! They get thirsty, so Buster presses yet another button and the drinks cabinet rises from the floor. Next it's dinner
time. The dining table has a circular railway track in the middle, in the center of that is
a small revolving tray with the condiments on it. A drawer bridge lowers from the wall, revealing the kitchen behind, along the track comes a toy train pulling low wagons
loaded with soup bowls. When the soup is finished the bowls are replaced on the train
and returned to the kitchen. Here they are put on a conveyor belt by the cook, they
travel along to a dish washer, are washed and return along another conveyor belt to
the cupboards ready for putting away. Back in the dining room, the dean congratulates
Buster on his achievement. Keaton stands up as do the dean and his family in acknowledgment of Buster. Buster bows, separating part of the track with his hand as
he does. The main course arrives. Round the track it goes, until it gets to the broken
section, the train comes off the track and heads straight for the deans' wife. Dinner,
train and all land in her lap. A mother cat is in the kitchen with her two kittens, and
when the cooks back is turned, the mother cat walks off, leaving the kittens alone,
they climb onto the train, stepping on the 'food's ready' signal bell on their way. Buster
starts the train again, and instead of desert, two kittens arrive.

The next day the dean has invited friends over for supper. At the same time the real
electrician arrives, bent on revenge. He walks in through the kitchen, wrench in hand,
scaring the cook in the process. She thinks he has a gun. He goes into the main control
room where there is a bank of plugs and sockets which route the control signal to the appropriate piece of equipment and starts swapping over as many things as he can. The
cook, meanwhile, has run down to the basement and hidden in Busters trunk. Buster,
of course, chooses this moment to go and get his trunk. He wonders why it is so heavy
and struggles up the basement stairs with it. He is pleased to get to the escelator for the
final part of his journey. He turns the switch, and nothing happens, he tries again with
the same result. The only answer is he'll have to walk up. Keaton gets about halfway up
and the electrician turns the escelator on again, but in reverse, Buster is on a tread mill.
The electrician turns the power off again at the same moment Buster stops to see how
far he has got. He is somewhat surprised to find he is still only halfway up. He trudges
to the top and puts the trunk down. He is standing to the side of the trunk looking away
and does not notice the escelator has been turned on again, the trunk descends, Buster crouches down and feels for the trunk ready to pick it up again. He can't find it, he turns round to look and see's it at the bottom of the stairs again. Perplexed, he is about to go
down after it when the escelator starts again, this time going up. The trunk shoots past
him, out the window and, into that pool! Buster can't get down the fast moving escelator,
so he slides down the banisters again and rushes outside. He pulls up suddenly as he sees
a hand emerging from his trunk, he runs back inside. The cook manages to free herself
from the trunk and tips herself into the water, climbs out taking a white sheet off the
clothes line to wrap herself in. She walks back inside the house past Keaton, who thinks
he's seen a ghost. Then the lights start flashing on and off, which scare him more. He
runs upstairs into the girls room, she is sitting on her bed. He stands there facing her
explaining what he has seen, as he is talking the bath comes out and knocks him over. Simultaneously the bed folds up trapping the girl. He helps her and then tries to go back downstairs. The escelator is still going up and Buster tumbles and rolls getting nowhere, suddenly the escelator stops, hurling him into the dining room. He jumps over the
drawbridge and runs into the kitchen where he sits on the conveyor belt. The conveyor
belt starts up, transporting Buster towards the dish washer. He jumps off quickly and
sits on the floor, plates start to hurl themselves out of the dish washer. Buster tries to
turn the switch off but nothing happens. This confuses Keaton, but the penny doesn't
drop.

Meanwhile, the family are eating their supper, the dining chairs start moving back and
forth and the condiments spin round faster and faster. The electrician is still hard at
work, switching over plugs. The guests and the dean go into the library, where the guests
are bitterly complaining about their treatment. The dean is equally annoyed and starts
shaking his fist at one of the men who turns his back on him, as he does so, a book
comes flying out on it's pole and hits the guest on the back of the head, returning just as rapidly. He thinks the dean has hit him and turns on him. Just then Buster enters telling
them about the hand he has seen. As he is telling them he sees the hand print of one of
the guests, who has left the room, outlined on the frosted window of the door. Buster
puts his hands over his eyes, as he does so, the drinks cabinet, that he happens to be
standing on, rises out of the floor. Still with his hands over his eyes, Keaton steps off it
into mid air, falling head first to the floor.

Suddenly the truth dawns on him. He rushes to the electrical control room and finds
the door locked. He gets a chair to stand on and looks in through the window over the
door. What he suspected is true. He rushes into the kitchen and gets armfuls of pots
and pans, throwing them through the window. The electrician keeps getting electric
shocks from all the metal work shorting out the bare wires, he jumps about among the
sparks. Buster is just coming back with another armful when the electrician bursts out
of the door knocking him over. A   chase ensues, culminating with Buster daring the electrician to follow him up to the top of the stairs. As the electrician starts out on them, Buster switches on the escelator at full speed and the inevitable happens. The electrician
is catapulted out through the window into the pool. Buster goes to follow, but can't
summon up the courage to jump. He needs the momentum of the escelator. He cannot
run down it, so he heads on down the banister, jumps on the moving stair way and is
also shot through the window. Not before gathering up the dean, who happened to be
crossing the landing at the same moment Buster headed for the window. Both end up in
the pool along with the electrician. The dean is furious, his daughter comes out of the
house to see what's going on and both of them agree, Buster has to go. He is upset by
this injustice and picks up an ornamental rock which he ties round his neck with the
clothes line, tying it like a neck tie. He jumps in the pool with his diploma. The girl
empties the pool quickly. The electrician has disappeared, but Buster is lying on the
bottom using the rock as a pillow. The dean fills the pool up again and walks beck into
the house. The girl, feeling sorry for Buster hesitantly empties the pool again, but
Buster is gone.

The final shot is of Buster floating out of a sewer outlet by the sea. Already sitting there
is the electrician.
