River of Flames

Bill and Jeff are discussing the best means of eluding Urko's troops when Judy appears and insists they come to the below world and bring the laser they rescued from the ship.

Realizing that Bill must be in the area, the army upscales its search. Arriving at the spot where they left the laser, Bill and Jeff see tire tracks and know the apes must have found the laser.
