College student Bailey Jones is plucked from his world by a mysterious and unpredictable force known as the Rift, which appears to move people at random from one world to another. Stranded on an alien planet, he is relieved when he meets a fellow human, the self-styled Riftmaster, who is prepared to assist him. Although curious about his new companion's real identity, Bailey hopes that, with years of experience of the Rift, this cosmic traveller can help him find a way to return to Earth. But first, as the two of them are ripped without warning from one hostile planet to another, Bailey must rely on the Riftmaster to show him how to survive.

Riftmaster, an adventure, an exploration, is concerned with loss, and letting go, while still holding onto your humanity and identity, even when life seems hopeless.
