While Detectives Briscoe and Green search for the killer of two underaged teenage girls who were drugged, bound and raped, they discover that one victim's older sister is also missing, but if found alive, could be the key piece of evidence against their prime suspect. When the beaten young woman is recovered but is reluctant to testify against her "boyfriend," Assistant D.A. Carmichael contests her story while fellow A.D.A. McCoy tries to keep the state's rapidly dissolving case intact.
