To cope with the difficult life away from Earth, colonists rely on the illegal hallucinogen Can-D, secretly distributed by corporate head Leo Bulero. New tensions arise with the rumor that merchant explorer Palmer Eldritch has returned from an expedition in possession of a new alien hallucinogen to compete with Can-D.
