A homeless man meets a medical school student who pays him to volunteer for a surgical procedure known as trepanation, drilling a hole in his skull, which ends up giving him the ability to communicate with the dark side of people’s subconscious minds.

Office drone Maria Barbizan leads what looks like a meaningless life. She’s lonely, and she doesn’t really exist, at her job or within her family. One day, she does everything we’ve all dreamed of – she throws her purse and old life in the trash, and joins an enigmatic contest to win… a car. Locked in a room with four strangers, each more eccentric than the next, she must go through a series of challenges – a “competition to probe the very essence of mind-body articulation”, lead by Homunculus, an intriguing and curious host.

Sinbad and his crew intercept a homunculus carrying a golden tablet. Koura, the creator of the homunculus and practitioner of evil magic, wants the tablet back and pursues Sinbad. Meanwhile Sinbad meets the Vizier who has another part of the interlocking golden map, and they mount a quest across the seas to solve the riddle of the map.
