Set in a world mirroring the mid-20th century, Bethelman embarks on a quest to unravel the mystery behind his amnesia. He finds clues pointing to a night of excessive drinking and an experimental drug given to him by Dr. Kamiroff. This substance boosted his ability to foresee events and, at the same time, erased parts of his memory.

It's a journey where Bethelman finds the chance to experience time renewed with clarity, offering a resolution where he chooses to relive those forgotten steps.
