Planet Express is facing foreclosure and the crew is trying to find a way to pay off the mortgage. Leela suggests they change the company into a commercial airline, but the men instead decide to make a pin-up calendar. Leela, Amy, and LaBarbara pose as models in skimpy clothing, forced to do so by a clause in their employment contracts, but the idea does not go smoothly. Professor Farnsworth then decides to convert the company into a private airline, but things go wrong when Fry and Hermes, who are piloting the plane, fall asleep and overshoot their destination by two days. The plane runs out of fuel and crashes on a planet made entirely of minerals with rivers of mercury.
