Inspired by Spaghetti Western films, Three on a Match is set on Mars in a hundred years, made habitable due to terraforming. Along its equator sits the cities that comprise civilization. Beyond this lies Nu West, the frontier which in many ways resembles the Old West. Three disparate men each learn of a stolen treasure and clues to its whereabouts. None of them know all the details of where the treasure is supposed to be, so, at times, they are forced to work together. They face many dangers, both individually and together, in pursuit of their quest, including each other.
