A family's air conditioner breaks down, and they call an AC repairman, Marvin, who charges them $500 to "fix" it. Unbeknownst to the family, Marvin simply turns the AC back on. Meanwhile, the family's son, Jeffy, becomes possessed by a demon and the family calls an expensive exorcist, also Marvin, who claims to perform an exorcism but actually just tricks them. Marvin eventually "exorcises" the demon by trapping it in a Buzz Lightyear toy and throwing it down the stairs. In the end, the family discovers that Marvin scammed them, and the AC was never actually broken.
