Les Challengers de l'Inconnu [Challengers of the Unknown] [Ace Morgan; Rocky Davis; Prof Haley; Red Ryan]; Mr. Tic-Tac-Toe [Dr. Bradford]; Herbert
The Challengers are asked by Dr. Bradford to deliver a vial to Washington, but they are forced to land in the desert. The guys split up to look for help, observed by Mr. Tic-Tac-Toe and his helper Herbert. Ace gets caught in an arroyo and is staked by Herbert to a giant Tic-Tac-Toe display. Red falls through a trap door and Rocky ends up behind bars before being added to the grid. Mr. Tic-Tac-Toe reveals his game to Prof and demands the vial he gave him as Dr. Bradford in exchange for his friends. Prof seemingly gives in, but switches the vial with one that knocks out the villains.
