Kyle Maclachlan stars as Jeffrey Beaumont, a square-jawed young man who returns to his picture-perfect small town when his father suffers a stroke. Walking through a field near his home, Jeff discovers a severed human ear, which he immediately brings to the police. Their disinterest sparks Jeff's curiosity, and he is soon drawn into a dangerous drama that's being played out by a lounge singer, Dorothy Vallens and the ether-addicted Frank Booth. The sociopathic Booth has kidnapped Dorothy's young son and is using the child as a bargaining chip to repeatedly beat, humiliate and rape Dorothy. Though he's drawn to the virginal, wholesome Sandy Williams (Laura Dern), Jeff is also aroused by Dorothy and in trying to aid her, he discovers his dark side. As the film nears its conclusion, our hero learns that many more indivduals are tacitly involved with Frank, including a suave, lip-synching singer, Ben, who is minding the kidnapped boy.
