In the small town of Chilan, Mexico, a rift in time and space overlaps a modern soccer field with a classical Mayan game of life and death. Emilio, a night shift security guard and referee, accidentally overlapped with the memory of a Mayan golfer from thousands of years ago, and activated the "Referee's Eye" system from the rain god Chuck - able to discern the hidden rules and costs of ancient rituals. He is forced to deal with supernatural organizations, the remnants of ancient priests and ambitious reborn people, using rules to mediate conflicts and prevent the town from turning into a bloody altar. And his encounter with Sophia, an archaeologist with the bloodline of the Guardians, involves a shocking secret that spans thousands of years: an unfinished sealing ceremony, and the awakening terror of the starry sky. They must join forces to decide the fate of the two eras with an ultimate game that combines ancient and modern rules as the battlefield.
