A double bill of double trouble. In 'Basket Case 2' Duane Bradley (Kevin Van Hentenryck) and his deformed Siamese twin, Belial, survive a near-fatal fall. They find a safe home with kindly spinster Granny Ruth (Annie Ross) - who is surrogate mother to a variety of mutants - and her beautiful granddaughter. All is well until a sneaky journalist attempts to flush out the Bradley brothers and their new friends turn nasty. 'Basket Case 3 - The Progeny' is the final part of the trilogy. Duane Bradley and his deformed brother Belial are special cases; having been taken in by kindly spinster Granny Ruth and her household of freaks, they are now ready to go on the road on a trip through the Deep South. However, Belial has now become father to his own monstrous sons, and, when the newborn infants are kidnapped by a pair of evil deputy sheriffs, vows to exact a terrible revenge.
