TRICK OR TREATS

Malcolm O'Keefe is surprised one morning at breakfast when two men arrive to bring him to a mental asylum so that his wife, Joan, will have him committed. After a brief struggle in the backyard pool, Malcolm is captured and taken away by the men in white. Several years later, Linda is called to babysit Joan's son Christopher on Halloween night while Joan and her new husband, Richard, attend a Halloween party in Las Vegas, where they are performing as magicians. Christopher plays tricks on Linda, such as using a fake guillotine, throwing a smoke bomb at her, and using a joy buzzer.

At the asylum, Malcolm contemplates his escape after having been there for nearly four years. Malcolm manages to escape with help from another inmate and vows to get revenge on those who put him away. After Linda calls her friend Andrea to bring film to her, Linda goes outside to look for Christopher. Malcolm enters the house in search of Joan and hides in the attic. Andrea enters the house, and Malcolm fatally stabs her, mistaking her for Joan.

Linda and Christopher go back into the house, and Brett calls Linda. After the call, Linda goes upstairs to find Christopher asleep. Linda goes downstairs, and Malcolm attacks her. She tricks Malcolm and runs outside and hides in the shed. Malcolm enters the shed and sees all his old belongings, reminiscing over them. Malcolm finds where Linda is hiding, only for her to escape again. She gets in her car, but it won’t start, and then she runs back to the house again.

Linda then barricades Christopher and herself in Christopher’s room. Unbeknownst to Linda, Malcolm burst through the other door to Christopher’s room and attacks Linda once more, this time to be fatally injured by the guillotine toy altered by Linda to become an actual one. After which, Linda goes downstairs to call the police, and Christopher takes Malcolm’s knife. The movie ends with a freeze-frame of Christopher about to stab Linda to death.

Linda defeats Malcolm with a real guillotine rigged from Christopher's toy, but as she calls the police, Christopher picks up Malcolm’s knife and approaches her, the film ending as he is about to stab her.

The ending flips the tables by having the seemingly harmless prankster child become the final, unexpected threat. Just when Linda believes she’s survived the night, the freeze-frame on Christopher’s potential attack suggests that the cycle of violence and twisted humor continues, leaving the audience unsettled and questioning where the real danger lies in this warped household.
