Synopsis
In an episode reminiscent of the first season episode "The Challenge", Professor Robinson and the Robot land the Space Pod on a planet, and Professor Robinson kills an attacking monster, only to discover that he has interfered with a contest where a highly intelligent alien who aspires to rule his home planet is being judged on how well he hunts. The alien forces Professor Robinson to take the role of one of the hunted animals in the contest, allowing the Professor one weapon. The weapon has a defect that imperils Professor Robinson, but the Professor outwits the alien and survives the ordeal.
