In 1970, Harmony, a small town in
New Mexico, is run by a small-time crime boss named Slue, who accepts the delivery of a
Lincoln Continental car stolen by his henchman Weasel, who brings it after killing a couple who was travelling with their child. When the crime boss finds the couple's baby in the backseat he wants to kill him, but he is stopped by his transvestite “wife”, Pearl. Slue decides to keep the baby - which Pearl names “Sonny Boy” - but he cuts out the boy’s tongue and raises him as a mute accomplice in their crimes, training and treating him like a wild dog, and sending Sonny Boy to kill anyone who wants to steal from or opposes Slue's grip over the town. When the grown Sonny Boy escapes and tries to make contact with the outside world, the attention he draws to his warped family results in darkly-humored mayhem. == Production and music ==
