Indebted to the wrong people, her manipulative manager, Doug, comes to her just before her big fight, begging her to do him one more favor by taking a dive. In the past, against her better judgment, Doug has managed to convince her to throw fights resulting in major beatings and landing her in the hospital. Her upcoming match is against a young, brutal fighter who just obliterated her first opponent. In their climactic showdown, Mya must decide to either help Doug or believe in herself and fight to the end, whatever the result.
