April Regan wrongly assumes that there is only one person standiing in the way of her gaining overall control of their late father's gangland firm. That person is her older sister Donna. Unaware that Donna has her own plans, April agrees to team up with her under the misconception that she is the only one with a hidden agenda. They are so focused on outwitting one another that they neglect to consider that there could be other contenders waiting in the wings with dangerous intent.
