Third-year emergency medicine resident Tin has to cope with a deluge of different patients every day. Up until the eighteenth, that is. Tin's life is transformed when university student Tol's car is overturned, and he's rushed to the emergency room in serious condition. That night doesn't end when Tin fails to save Tol's life, though. When Tin next wakes, he finds himself in a time loop, a loop he won't be able to leave until he's altered Tol's fate.
