The women of Lost in Space are featured in their very own episode while the boys are out installing communications equipment. Smith is left in charge (boy is that a mistake) and he "cleans" their weapons, but cannot remember how to rebuild the weapons. This leaves the J2 crew defenseless.

A creepy creature stalks the Robinson women however they think a small dog is to blame for raids on food and other mischief.

Les Robinson découvrent un vaisseau spatial qui test le sommeil cryogénique. Ils découvrent également un chien de vingt ans endormi. Plus tard, dans la nuit, on a volé de la nourriture et l'on entend des grognements. Il ne s'agit pas du chien, mais d'un mutant poilu qui attaque Judy. Heureusement, c'est le chien qui va la sauver.
