For the exiles from a blistering Earth, Mars is a lonely place, made bearable only by drugs, specifically Can-D, which translates those who take in into a shared hallucination of a Barbie-esque world.

But the new drug Chew-Z promises more than thateternal life itself. But it a world where everyone is tripping, no promises can be taken at face value. When those promises come from Palmer Eldritch, who may be human, alien, or god, they can be trusted even less.
