In a dystopian future where the remnants of humanity dwell in an underground metropolis, players take on the role of Eli Starker, a street-smart detective with a knack for piecing together the bizarre. One evening, while following a mysterious shadow that seems to have a mind of its own, Eli discovers that various factions are hunting down a group of shadowless individuals—people who have mysteriously lost their shadows and, with them, their pasts. Players must navigate the twists and turns of the underground world, choose whom to trust, and uncover the truth about their own shadow's origins, leading to an explosive climax redefining identity and existence.
