忧郁男孩 (1997)

Living in the rural Texas panhandle is a dysfunctional family: an abusive dad, a Vietnam vet with a war wound that's left him impotent; a compliant wife and a son of about 20, who have an incestuous relationship at the insistence of the dad; and, two small sons who look a lot like their brother. The dad harbors a secret, and he goes to murderous lengths to keep it hidden. The young man, Jimmy, who sleeps out in the shed, has suspicions, but little comes out until a Yankee woman of middle age comes to town looking for a dead private eye. And why does dad keep calling Jimmy, "little boy blue"?
