Twenty years have passed in a flash. Rayden (Ewan McGregor), who has gone to a foreign country, once again set foot on his hometown of Edinburgh. As soon as he came back, he ran into Shiba (Ewen Bremner), who was desperate and tried to commit suicide. It turned out that Shiba not only failed in marriage but also became addicted to drugs again. Encouraged by Rayden, Shiba decided to use writing to heal the scars in his heart. Later, Rayden found his former best friend Sick Kid (Jonny Lee Miller), who beat Rayden because of a previous dispute. After that, a revenge plan slowly took shape in his mind. At the invitation of Sick Kid, Rayden decided to open a brothel with Sick Kid, and then Shiba, who was good at design, also joined in. On the other side, Begbie (Robert Carlyle), who was imprisoned, successfully escaped from prison. After learning the truth of the incident that year, he decided to find Layton and seek revenge on him.
