Dorian (Luke Wilson) and Angus (Jake Busy) try to "scare the devil" out their stepfather by chasing him with a helicopter -- but in an unplanned accident, it kills him. To make matters worse, the old man has been having an affair with Sally (Drew Barrymore), a young employee at the local Burger-Matic who's now pregnant and searching for a substitute father for her child. Things really get complicated when she thinks Dorian could be the one.
