Lost in Space Season 3 Episode 1 Condemned of Space

Launching into space to avoid a rogue comet, the Robinsons encounter the Vera Castle, a floating prison full of frozen criminals. On a whim, Doctor Smith frees Phanzig, because how dangerous could a man playing Cat's Cradle with a bit of twine be? Then Phanzig forces Doctor Smith to take his place! When Phanzig discovers that the clock that regulates length of sentences stopped long ago, he frees other prisoners to launch a rebellion. In the midst of all this, the robot guard mistakes Don for a prisoner and freezes him solid!
