Supreme Sentinel has noticed a lot of young Elite Force Trainees have been going missing in recent months, and not much is being done about it. She decides to go undercover, joining the Elite Force training program and naturally acing it, to see if whatever is happening to the missing recruits, will happen to her. It isn’t long before she runs into Nancy Blackwood, leader of the Darkhearts, who confesses to what she thinks is a basic trainee, that she has been capturing young heroines and selling them off as peace offerings to rival gangs to extend her criminal network. She has the same plan for the blonde in front of her. Supreme Sentinel is disgusted and the fight is on. Nancy soon finds this ‘trainee’ is a cut far above the others, but Supreme Sentinel also makes the mistake of underestimating Nancy, and having her strength drained. Nancy wants nothing more than to capture the Sentinel and turn her into a prize captive. Can Supreme Sentinel bring down Nancy? Or become the property of villains?
