Angel of Death 2: The Prison Island Massacre.

A young girl is wrongfully arrested and sent to an isolated prison located on a small island. She claims her innocence, but is still subjected to all the torture and humiliation that all prisoners face at the hands of Mrs Steele, the sadistic warden. Help is on the way in the form of a group of mercenaries hired by the girl's father. They will do anything to get the job done, even if it means turning the island into a war zone.
