Phillip Filmore is a naive, 15-year-old, preoccupied with sex, who develops a crush on Nicole Mallow, the new 30-something, French housekeeper and sitter to look after him when Phillip's father is out of town for the summer on a business trip. But Mr. Filmore's unscrupulous chauffeur, Lester Lewis, takes advantage of Phillip's crush on Nicole to hire her to seduce the youth, then draws her into a plot to fake her own death in a blackmail scheme aimed to drain Phillip's trust fund. An immigrant housemaid seduces a 15-year-old boy and later fakes her own death as part of his chauffeur's blackmail plot. Troubles arise when the two start to fall in love.
