The four-man crew of the spaceship Dark Star is twenty years into their mission to locate and destroy unstable planets that pose a threat to future Earth colonies. The spacemen, led by Lt. Doolittle (Brian Narelle), dump bombs on the unstable planets then blast away at hyperspeed before they explode. Their lives between detonations are boring and tedious; the crew is so disengaged and disinterested in their jobs that they barely notice that Dark Star has been damaged in an asteroid storm, and that the malfunction could have disastrous consequences for their next bombing run.
