Randy Mason (Chris Carrara) is a teenage tech whiz who lives in a suburban neighborhood located somewhere in the state of California with his mother Marti (Derya Ruggles), who creates designs for an ad agency and his father Brent (who's away for the duration of the film on a business trip).
He shares the hobby with his good friend and love interest Judy Riley (Jessica Bowman), an avid baseball player and shows her the local model home which serves as his secret hideout.
Randy reluctantly lets him take it, but tells him the controller is locked by at night with the others, so Ben insists he bring it to school the next day to give to him.
Getting the blame for it because no one saw Ben, Randy is expelled from the school and arrives home to hear Marti saying on the answering machine (she was stressed and too upset to think at the moment) that she heard about what happened and is going to confiscate all of his models.
The three robbers (having robbed a convenience store, but left the money behind by accident) decide to break into and hide at the model home until the road blocks the cops set up for them are cleared away in 3–4 days.
The ill-tempered Delbert (embarrassed by his real name and insistent on being called Del) has a gun which is why they have been labeled on the news as armed and dangerous.
Randy also tries to trip the burglars up by using Gunther to put a tack in Richie's shoe, but he and Louis just barely avoid stepping on the alarm pads.
Judy and her family get home late from the game and go straight to sleep, not noticing that Marti called earlier and left a message on the machine.
The police arrive and arrest Louis and Richie (and presumably Delbert as well), Randy is reunited with Marti and Jamaal and Mrs. Williams with Bluto (who ran away from her).
