The story reunites the entire cast from the series, effectively picking up where the season four cliffhanger ended. Jarod (Michael T. Weiss), Ethan, and Miss Parker (Andrea Parker) are alive after the bomb explosion on the train. Jarod is now posing as an agent of the National Security Agency; he is part of a task force assembled to find the "Chameleon", a killer who displays all the adaptive traits of a Pretender.
