SYNOPSIS

Former FinCEN director Raymond King meets with the mysterious assassin Anaïs to ask her help locating a Salvadorean family, offering only a dated photo of the parents and their young son. Anaïs doesn't respond to the offer but warns King he's been followed. King is assassinated in the ensuing gunfight while Anaïs walks away unscathed. King's protege and current director of FinCEN, Medina, identifies his body and sees "find the accountant" written on his arm and decides to take up the case.

Medina, despite being mistrustful of Christian Wolff's illegal activities, asks him for help finding the family in the photo. Wolff organizes a collage of information which shows that the family in the photo fled from El Salvador to Los Angeles, encountering various hazards along the way. Cobb, the man tasked with killing Anaïs and King, informs his supervisor Burke who tells him to continue pursuing Anaïs lest she realize what Burke did to her.

Christian invites his estranged brother, Braxton, still an assassin, to help with the case. Justine, still residing at the New Hampshire compound where she met Christian, works with a group of autistic children to hack into different technologies to help Christian. Their group manages to find a photo of Anaïs but are unable to identify her. Uncomfortable with their illegal methods, Medina breaks from the group. She visits a hospital mentioned in one of King's reports, where she discovers Anaïs is actually the mother from the photo. Anaïs was involved in a critical accident and after losing her memories, she developed intense combat skills before escaping. Batu, a contractor for hit men, sets a contract for Medina which Braxton rejects. Justine warns Wolff and he arrives after Anaïs has wounded Medina.

Braxton and Christian realize that Anaïs' still living, autistic son Alberto is being held captive at a prison camp in Juarez with other children of trafficking victims, separated from their families. They assault the compound and manage to save Alberto and the rest of the children after killing Cobb and the other guards. Justine blackmails Batu into canceling his contract on Medina. Anaïs, having regained some of her memories, realizes Burke is the person who imprisoned her son and killed her husband in Juarez. She finds Burke in hiding and kills him. Justine and the autistic children prepare to welcome Alberto to their facility in New Hampshire, and Braxton and Christian discuss going on a brotherly camping trip.
