Xi is a police detective, and his heart is still looming over the tragic death of his son a few years ago. Now his wife's leukemia has reached an advanced stage. While he was talking to the doctor in the hospital, the doctor suggested that he take his wife home. He received news that Horibe, his friend and colleague on the team, had been injured by a habitual offender they had tracked for a long time and was seriously injured. The Horibe injury was not caused by Nishi, but because the situation at the time was extremely dangerous and they were already unable to deal with it. Horibe can only use a wheelchair now. Xi was disturbed by the loan sharks, and they forced him to pay off the debt. Xi also wanted to comfort his wife who had just returned home, and also wanted to support Tanaka's widow. The young police detective Tanaka died in an ambush. Nishi always thought he was responsible for Tanaka's death. He also tried to get close to Horibe. After being injured, Horibe was abandoned by his wife and daughter and lived alone at the beach. All this made Xi feel exhausted. Xi decided to leave the police station and accompany his wife on a final trip, trying to put everything to an end.
He bought a stolen taxi from an old car dealer, converted it into a police car, put on a police uniform, and went to rob the bank. After he succeeded, he paid off the debts owed to the loan sharks, gave a portion of the money to Tanaka's widow, and mailed a pack of paint, brushes, canvas, and an artist's brush to Horibe. Horibe wanted to paint a long time ago, but he didn't have the money to buy these utensils. After all this was done, he and his wife went to Snow Country first, then to the beach, under the tracking of the gang and police friends, embarking on a journey with no return
