Red Dwarf, a mining ship around the moons of Saturn, runs into trouble and one lone human becomes the spacecraft's sole survivor.

When Rimmer and Lister break the light barrier, the crew have visions of the future. Rimmer sees a death, and Lister's future appears explosive.

After Rimmer's data disc becomes faulty, he wakes up with a stranger's arm that seemingly has a mind of its own.

Lister discovers some amazing facta about cats after learning to read the language. Plus, Rimmer find an extra-terrestrial capsule.

Lister contracts a rare form of pneumonia in which his hallucinations become real. They take the form of the extroverted and introverted parts of his nature, which materialise in person.

Rimmer learns how to duplicate himself, and decides to move out from the quarters he shares with Lister to move in with himself.
