He also unveils his recent ambition, to write a history of Leith. As the two converse, Sick Boy considers the merciless trait of opportunity and threat accompanying Begbie's release.
Meanwhile, in Amsterdam, Mark Renton is co-owner of a successful nightclub.
One night, a DJ from his hometown (Carl Ewart from Welsh's previous novel Glue) plays at one of his clubs and recognises him.
When Sick Boy learns of Terry's operation, he offers the use of the upstairs bar to shoot some scenes.
During their first meeting, the group begins planning to shoot a full length adult film.
Simon 'Sick Boy' Williamson leaves the London crack scene and returns to Leith when he comes into ownership of his aunt's pub.
Convinced that the area is destined to become a social and cultural hub, Simon decides to focus his energy into making the pub an upper class establishment.
One example is the fact that "Spud" has received his share of the drug money, which is shown in the film, but only alluded to in the book.
The novel is divided into three sections, each of which comprises chapters with different narrators.
Nikki Fuller-Smith is a university student who works part-time in a massage parlour.
Rab, a university acquaintance, introduces her to his friend Terry Lawson and his underground, home-made pornography operation. Danny 'Spud' Murphy has been regularly attending group sessions in an attempt to kick his drug habit.
Spud's chapters are just narrative, Begbie's are in capitals, and Nikki's are quotes from the chapter, for example "... Each narrator is associated with a distinctive prose style.
