In present-day İzmir, a team of archaeologists unearth what they believe to be an ancient cultic chamber. Hidden beneath the earth, they find a sarcophagus engraved with grapevines and riddles in dead languages. What they do not realize—until it is too late—is that they have awakened Dionysos, the ancient Greek god of wine, madness, and ecstasy. Freed from his slumber, Dionysos brings with him a supernatural wave of chaos, a delirium that begins to spread through modern society like an invisible infection.
