The third installment of the “Law & Order” franchise takes viewers deep into the minds of its criminals while following the intense psychological approaches the Major Case Squad uses to solve its crimes.

English professor Susan Selky lives alone in a Brooklyn apartment with her young son, Alex. When Alex fails to return home from school one afternoon, a frantic Selky contacts the police. Detective Al Menetti, a father himself, takes an interest in the case that quickly turns into an obsession. As a devastated Selky struggles to come to terms with Alex's disappearance, Menetti steps out from behind the badge to continue investigating.
