The Jupiter 42 is out of fuel and has to pass through the Bermuda Quadrant in order to get to a fueling station. On the way they run into the ghost ship USS El Dorado.

Chode's grandpa Benito and a few of his pals have escaped from the Fun City Retirement Home, where the old folks' brainwaves were being used to power an amusement park. Naturally Chode does not believe this, sends them right back and visits 7 ½ Flags.

The crew walks out on Chode and find new jobs on a Cruiseship in space. Meanwhile, Chode hires a group of illegal alien aliens to run the Jupiter 42.
