A number of very young nubile women are all prisoners in a stockade in some remote area and they break out of prison by killing loads of guards in every way imaginable and fight their way to a boat. This was fun to watch - but then their boat sinks and they wash ashore on an island. They encounter what seem to be guerrillas and join them and go through a very lengthy training period to become lunatic frog women . I had sort of hoped the title indicated that somehow there were some mutated forms of frog women in this film, but that is not the case. Finally after a lengthy lull in the action, the women are ready and attack what appeared to be Vietnamese soldiers in a pretty brutal battle.
