Aboard the Red Dwarf, Dave Lister smuggles aboard a cat and is consequently confined to suspended animation for the crime. During his time in stasis his bunkmate Arnold Rimmer is forced to perform the maintenence duties alone and inefficiently repairs the drive plate, causing it to blow and subjecing the entire crew to deadly radiation.
Lister and Cat prepare to go into stasis while Red Dwarf goes to light speed until they get back to Earth. Rimmer does not want to be turned off, so he demands to be left on for the journey, even though he will be by himself. Unfortunately they reach light speed 22 hours before they expected and don`t get to go into stasis after all.
Lister finally gets a reprieve from Rimmer`s boring inventory checks and goes for a drink. Sitting in the empty bar, he flashes back to a disco that he attended with his mates, Petersen, Chen and Selby; and finally realises that he is alone. After he wallows in self-pity for being alone in deep space, Lister pleads with Rimmer to allow him to create a hologram of Kristine Kochanski.
Holly notices a pod floating in space and Rimmer orders that it be salvaged, convinced that it contains alien life forms, even though Lister realises that it is a Red Dwarf Garbage Pod, jettisoned from the waste disposal unit. Meanwhile Lister is researching the Cat`s religion and discovers that their race which evolved from his pet, Frankenstein, now have his image as their God.
After visiting the officers living quarters aboard the ship before it has been decontaminated, Lister wakes up with a case of pneumonia and begins to hallucinate in his sleep. His dreams become real however, when it begins to rain fish in their room, and the Mayor of Warsaw appears and then spontaneously combusts in front of Rimmer.
Lister gets more that he bargained for when the disk supposedly containing Kochanski`s hologram is actually a copy of Rimmer. The two Rimmers decide to move in together leaving Lister who is all too happy to be rid of them. However, the two Rimmers are so alike that they cannot get along and continually insult and berate each other. Lister discovers a tape of Rimmer`s death on which he utters the words "Gazpatcho Soup" before his demise.
