Jack Armstrong
INTO THE CHASM
S1 E4:
Jack and Betty are saved from the fiery pit by Umala (Russ Vincent), a native who now realizes that his enemies are the white men working for Grood. The latter orders his henchmen to shoot Jack and his friends on sight. Blair and his fellow henchmen combined with Princess Alura natives maneuver the adventurers toward a dangerous rope-bridge spanning a chasm.
