Set in the summer of 1976, the film follows the adventures of Drew Tate (Larenz Tate), a shy 16-year-old from upstate New York, when he and his family spend two weeks with affluent relatives on Martha's Vineyard. Drew's parents, Kenny (Joe Morton) and Brenda (Suzzanne Douglass), worry that their son is emotionally disturbed. His favorite companion is a doll, in which he names Iago (after the character in the Shakespeare classic Othello), with which he engages in animated conversations. They also fear that a fire he accidentally set in the family garage foreshadows a future as an arsonist.
