The arrival of aliens on Mars throws the teenage Joe Maya and his friends into an unexpected adventure.

While Joe finds his bearings on the El Shank, Director Hazard seeks a way to use the aliens to his advantage.

The El Shank's plan to break away from Phobos is complicated when Hazard threatens Joe and Jenny's families.

While the Mars government tries a new tactic to exploit Joe, the Radorians reveal their true reason for coming to Mars.

Joe's attempt to negotiate with the guerrillas' leader only makes things worse when Hazard attacks the village.
