Foul Play synopsis
Librarian Gloria Mundy (Goldie Hawn) leads a relatively uneventful life. When she looks to shake things up, she somehow winds up in the middle of an assassination plot against the pope. Calling the police, Mundy meets the hapless detective Tony Carlson (Chevy Chase), who takes the case. During the course of the investigation, the two fall in love, but the assassin (Marc Lawrence) is still after Mundy -- and anyone with her -- to keep her from foiling the plot.
