On a dark winter night, Ji-soo, a man tormented by his past, wakes up in an unknown place, suffering from amnesia that prevents him from remembering how he got there. Anguish consumes him as he tries to piece together the fragments of his life. With the help of his best friend, the charismatic yet enigmatic Hyung-seok, he begins to navigate through fragmented memories and confusing visions. But the deeper he delves into his memory, the more he realizes that some secrets are better left hidden.
As the story unfolds, Ji-soo is confronted with the revelation of a murder that changed his life forever and seems to be somehow connected to his mysterious amnesia. His quest for the truth leads him to uncover a dark encounter with his own reflection—half truth, half lie—and the line between friend and foe begins to blur.
Relationships become complicated when a figure from the past, an seemingly forgotten woman, returns to unravel an enigma she has been guarding jealously. Danger lurks in the shadows as Ji-soo investigates, and memories emerge like shadows from a past that refuses to be buried. The climax arrives when he faces the consequences of his actions and the painful truth he has been avoiding, challenging his understanding of friendship, loyalty, and regret. A night that began as mere confusion transforms into an unpredictable journey toward self-discovery and redemption.
