When a wealthy married couple is murdered execution style, the SVU team quickly ascertains that the victims had been laundering money for a Colombian drug cartel--the same criminals who had previously ordered the shooting of former Assistant DA Alexandra Cabot (Stephanie March), forcing her into the Witness Protection Program. In order to put away the elusive hitman known only as "The Ghost" (Bryan F. O'Byrne, Cabot must emerge from hiding and provide testimony. . .even if it means sacrificing her life in the process.
