A man is living two lives. He is a private detective in a dystopian cyberpunk future trying to solve a triple murder. But when he falls asleep... he wakes up as a wandering adventurer in a barbaric fantasy world where magic exists. Is he two separate people? Or is he a third person that has undergone a psychotic split? He jumps back and forth from sword-wielding barbarian to jaded private eye trying to solve the brutal crime. But the bigger question is, can he merge these realities without losing himself?
