Whilst Dave Lister spends a week in the medibay with a bout of space mumps, Red Dwarf picks up an escape pod from a prison ship that was transporting dangerous criminals.
Arnold Rimmer and Kryten discover this and inform the others they learned that the ship suffered a revolt that destroyed it and only two people managed to escape – female prison guard Barbara Bellini, and a psychotic mass-murdering simulant.
[6] Taking influence from their own Red Dwarf novels, writers Rob Grant and Doug Naylor altered some of the historic facts of the show.
The ending was also changed at the last minute, after a scene earlier in the episode was cut where a giant bird dropping lands on Lister after he littered in the Justice Zone gardens.
[10] For the futuristic Justice Zone set the crew used the nearby Sunbury Pumphouse, a disused water pumping plant near the Shepperton studios.
Lister thinks that he could disguise himself with a turban and say he is from India, whereas the Cat replies saying he could "paint orange and black stripes on the side and tell her you play quarterback for the Bengals".
The simulant's overall appearance is reminiscent of the Borg from the Star Trek franchise, whilst his accent references the replicant Roy Batty in the film Blade Runner.
