Jamie Waterman is returning to the Red Planet, this time in charge of an expedition in which he hopes to demonstrate that one can study Martian life not only for the sake of the pursuit but more, that it can be profitable. Waterman also hopes to revisit a part of the canyon where he thought he spied a primitive cliff dwelling during the first Martian mission. But this second voyage to Mars brings trouble right away as Waterman clashes with Dex Trumball, the son of a billionaire who is backing the expedition. Dex wants to turn the planet into a tourist attraction, while Waterman wants to preserve the planet solely for scientific research. To further complicate matters, both men are attracted to the expedition’s beautiful psychologist, Vijay Shektar, who can’t seem to decide which of the two men she prefers. On top of all of this confusion, it seems that another member of the team may be trying to sabotage the mission while the elder Trumball is pulling strings in order to force Waterman to step down as the expedition’s leader.
