At the funeral of a double agent, someone attempts to kill the Chief and KAOS' Chief. Only one agency could be responsible, the new third spy network, ACB (Atrocities, Cruelities, Brutality). Its leader is Kubacheck, who is offering CONTROL agents the choice of joining his network or dying. Kubacheck's one weakness is an inability to get over a loss at ping pong to The Masked Marvel. Max goes undercover as the marvel to smoke out Kubacheck, and he's accompanied by Samuels, a new CONTROL agent. In Istanbul, Samuels reveals himself as Kubacheck and he forces Max to play a game of ping pong and the winner gets to live.
The ACB reference is for ABC, the third broadcast network (yes, there used to only be three), which finally was starting to pick up in the ratings.
This episode is a brilliant parody of I Spy as Max plays Robert Culp and Samuels plays Bill Cosby beautifully.
Robert Culp has an absolutely hysterical cameo as a waiter - "but me no buts, sir."
