Nathan, Devis and Kenzy arrive on Mars after a six-month journey from Earth. They've come to set up a Star Cop base, but Mars is a very different environment from the one they're used to on the Moon.
Nathan and Kenzy find themselves marooned in the Martian desert with a prisoner whose friends will soon arrive to attempt a violent rescue. Help arrives in the form of a reclusive colonist.
After the Star Cops receive a cryptic message about a man who may once have worked at a colony in the Argyre Basin, they make their way there to investigate.
A scared medic, on the run from her colony, seeks the help of the Star Cops. She offers information about a crime, but she demands legal immunity, and guarantees for her safety before she'll talk.
