Sinner's Blood

When their mother dies, two sisters go to live with their aunt and her family consisting of a horny uncle, a lesbian cousin, and a slow witted male cousin. They go to a small southern town where they later encounter both local idiot guys and a nasty group of bikers who come to town to party. The inept bikers have a deadly secret besides just fighting each other. You'll be shocked when the last 10 minutes of the film turns into a big biker pill party!
