Suzanne is a crooked small-town mayor who pockets illegal money and looks the other way while a local manufacturer dumps industrial waste into an abandoned mine shaft. Unfortunately, she discovers that her partner has also been illegally dumping dangerous toxic substances and that they are poisoning the town water supply. Suzanne's attempts to stop him backfire and she is killed, but not before she tells her ex-husband the sheriff about the whole fiasco. When Suzanne's estranged sister Sunny learns of the murder, she rallies the former members of an all-female commando team to go to the town and get revenge. The film features plenty of kickboxing action.
