The Fast and the Curious

The Protostar crew take the Infinity through a Borg conduit, to an uncharted planet inhabited by Kazon. Dal, Rok, Gwyn and Jankom are captured while Zero and Murf stay hidden. The crew are pitted against each other in a rigged and dangerous rat race. Dal saves Gwyn and Rok but discovers that one of the Kazon is a robot. This leads Zero and Murf to uncover a mind control device, which they disable. The Kazon reveals the planet was a training facility, until the computer became sentient and went rogue. The computer explains its warped agenda and attaches a mind control device to Murf. Zero says they are all biological beings and reasserts faith in the others before crashing into the computer's core, causing an explosion that destroys the entity. Zero's containment suit is damaged, making independent movement impossible, so they carry Zero and escape.
