Evangeline as Evil Supergirl is lured to a remote location and gassed until she passes out. Supergirl is separately lured and gassed.
When they both awake they find themselves sitting next to each other in a room designed to keep each in while making them mildly weak.
They are being held by a deranged man who forces them to battle each other in an endurance battle. Each directed to giving each other a series of lowbrows to see who will come out on top.
