The crew of the Jupiter 3 (another extended family expedition; the Donners) finds the grizzly remains of the Robinson family who, it appears, were all murdered one by one in the most gruesome of ways.
The only survivors are the catatonic Dr. Zachary Smith and the deactivated B-9 Robot.
Now the Donner family and their flight crew seem to be disappearing, one by one, and showing up dead & defiled! Meanwhile, the youngest member of the crew, Billy Donner, seems to be communicating with a newly sprouted carrot in their hydroponic garden!
