Carl, the ex-member of L.O.V.E M.U.F.F.I.N kills every member of the organization in order to have a entire Tri-State Area to himself. Candace Flynn Fletcher, leader of the Resistance, is captured by Carl. Carl gives strict orders to her to kidnap several children so they can be trained to be a army of his otherwise. And in he states that if she refuses, he will kill her brothers. Candace, only wanting her brothers to have freedom, does Carl's bidding.

Soon, Carl has a army of physically trained slaves doing his bidding and nearly everyone else becomes a regular slave of his.
