A big (300 lbs.), small town crook and his hairy-chested, cigar-smoking transvestite "girlfriend" (played by David Carradine in drag) find an infant boy in the car of a couple they just offed, and raise it caged like an animal, teaching "Sonny Boy" to kill and steal on command. Now the wild child with no sense of right or wrong has escaped and the couple sees its experiment in "child development" go disastrously haywire.
