Keaton plays a teller at a successful bank. Unbeknownst to him, the manager at the bank and his gang are planning on pulling off a robbery and hiding in an old house which they have rigged up with booby traps and effects to make it appear to be haunted. After a mishap that afternoon with Keaton getting glue all over the money and himself, he almost thwarts the gang’s robbery but when the owner of the bank walks in and sees Keaton armed with a gun he assumes it was he who tried to rob it. Keaton flees and takes refuge in the old house; however, a troupe of actors from a theatre production are also in the house and are clad in their scary costumes (ghosts, skeletons etc) leading Keaton and the gang of robbers to believe the house actually is haunted. After Keaton has many encounters with the “ghosts” and the house’s booby traps, he discovers the scam and the manager is revealed as being behind the robbery. As the manager is about to be taken away, he hits Keaton over the head and knocks him out before escaping. Next we see Keaton being awoken by two angels at the foot of a large stairway which he ascends all the way to Heaven. He asks Saint Peter to be let in but is denied and is sent all the way down to Hell. However, this is all revealed to be a dream sequence as Keaton regains consciousness in the house seconds later.
