While moon-hopping in the
Starbug,
Arnold Rimmer and
Kryten become separated in a planet-quake while claiming a planetoid for the Space Corp. Badly damaged, Kryten detaches his arm, and sends it back to
Red Dwarf for help. The arm scares
Dave Lister and
Cat at first, since
Holly described it as a tarantula-like creature when it arrived. Taking another
Starbug, the pair track down Kryten near the wreckage and repair him. On the search for Rimmer, the surroundings lead Kryten, Lister and the Cat to conclude that they've landed on a psi-moon: an artificial planetoid that can tune into an individual's psyche and adapt its terrain to mimic his mental state. This psi-moon has appeared to emphasize Rimmer's mostly dominant negative qualities, with his positive ones being weak and represented by a graveyard. When the group find Rimmer, they discover him imprisoned by hooded legions of his negative emotions and The Unspeakable One—a creature made of his self-loathing, with the hologram having been given a physical presence as a side-effect of the moon's transformative abilities. Attempting to rescue him, they find themselves struggling against The Unspeakable One, until it retreats when Kryten reassures Rimmer they won't leave him behind. When they find their
Starbug trapped in quicksand, Lister and Kryten conclude the only way to break free is to show love for Rimmer and boost his self-confidence. In response, Rimmer's self-respect and confidence emerge from the graveyard as musketeers and slay Rimmer's personal demons, allowing the group to escape. After leaving the psi-moon, Rimmer gets the others to admit that they only pretended to like him just to escape. ==Production==
