This season, the vigilante twins Eric and Erica Cross are teaming up with the very person who has been trying to put them in jail for murder. Detective Ryan finds himself seeking the help of the twins to find his missing daughter, Layla, who was taken by the twins' own sister, Robin Cross. The task becomes an undertaking after it is discovered that Layla was, in fact, taken from Robin and given to higher ups in the trafficking ring. Time is of the essence, as they only have days before Layla is auctioned off.
