Director David Lynch crafted this hallucinogenic mystery-thriller that probes beneath the cheerful surface of suburban America to discover sadomasochistic violence, corruption, drug abuse, crime and perversion. 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 (Isabella Rossellini) and the ether-addicted Frank Booth (Dennis Hopper).
College student Jeffrey Beaumont returns to his idyllic hometown of Lumberton to manage his father's hardware store while his father is hospitalized. Walking though a grassy meadow near the family home, Jeffrey finds a severed human ear. After an initial investigation, lead police Detective John Williams advises Jeffrey not to speak to anyone about the case as they investigate further. Detective Williams also tells Jeffrey that he cannot divulge any information about what the police know.

Not satisfied with the police's pace, he and the police detective's daughter carry out their own investigation.
