Section 1: Kicking While watching a
Jean-Claude Van Damme video, Mark and Simon (a.k.a. Sick Boy) decide to go and buy heroin from Johnny Swan (also called "Mother Superior") since they are both feeling symptoms of withdrawal. They cook up with Raymie and Alison. After being informed that he should go and see Kelly, who has just had an abortion, Renton goes home to finish his video instead. Mark tries to come off heroin by acquiring a bare room and all the things he will require when coming down (canned soup, headache medicine, and pails for vomit). When withdrawal begins to set in, however, he resolves to get another hit to ease the decline. Unable to find any heroin, he acquires
opium suppositories which, after a bout of diarrhoea, he must recover from a bookie's lavatory. Simon attempts to pick up girls while being annoyed by Mark, who wants to watch videos. Sick Boy eventually loses Renton. An infant, Dawn, later dies. Her mother Lesley is a heroin addict and acquaintance of the group. The cause of death is unclear; characters speculate that it may have been a cot death or caused by neglect. The Skag Boys are unsure of how to respond. Sick Boy becomes more emotional and distressed than the others and eventually breaks down, stating he is kicking heroin for good. Simon does not explicitly state that he was the child's father. Mark wants to comfort his friend, but is unsure how and cooks a shot for himself to deal with the situation. A sobbing Lesley asks him to also cook her up a hit, which Mark does but makes sure he injects himself before her. After an argument with his girlfriend Carol, Second Prize meets Tommy in a pub, and Tommy confronts a man who is punching his girlfriend. They are shocked to find the woman supports her abusive boyfriend instead of her would-be liberators by digging her nails into Tommy's face, inciting a brawl. While the couple slips out unnoticed, Tommy and Second Prize find themselves taking the blame for the whole affair from the pub locals. Spud and Renton, who have been assigned interviews as part of their job-seeking benefits, deliberately fail to get jobs, while attempting to obscure that it is deliberate.
Section 2: Relapsing Renton, Begbie and their girlfriends meet up for a drink before going to a party, but it ends when Begbie throws a glass off a balcony, hitting someone and splitting open their head, setting off a pub brawl. Tommy visits Renton's flat (shortly after Renton relapsed) after being dumped by his girlfriend. Renton reluctantly gives him heroin, setting off Tommy's decline into addiction,
HIV/AIDS, and later, death. Later, Renton's brother Billy and his friends Lenny, Naz, Peasbo, and Jackie are waiting for their friend Granty to arrive for a game of cards, as he is holding the money pot. They later find out that Granty is dead and his girlfriend disappeared with the money, prompting them to beat Jackie, whom they knew to have been sleeping with her.
Section 3: Kicking Again Begbie and Lexo pull a crime, so Begbie decides to lie low in London with Renton. Spud kicks heroin, and visits his grandmother, where his mixed-race uncle Dode is staying. Dode has had many troubles with racism growing up. One day, he and Spud went to a pub and were assaulted by skinheads. This abuse led to a fight, which left Dode hospitalised, where Spud visits him. Renton kicks heroin and is restless. He picks up a girl at a nightclub, Dianne, unaware that she is only fourteen. He is later forced to lie to her parents at breakfast the following morning. Despite his guilt and discomfort, he sleeps with Dianne again when she appears at his flat. Spud, Renton and Sick Boy take
ecstasy and stroll to
the Meadows where Sick Boy and Renton try to kill a squirrel but stop after Spud becomes upset, remembering Dawn. Mark is ashamed and Spud forgives him.
Section 4: Blowing It Renton and Spud are in court for stealing books. Renton gets a suspended sentence owing to his attempts at rehabilitation, while Spud is sentenced to ten months in prison. Renton relapses and has to suffer heroin withdrawal at his parents' house, where he experiences hallucinations of Dawn, the television programme he is watching, and the lecture provided by his father. He is later visited by Sick Boy and goes out to a pub with his parents, whose enthusiasm acts as a veneer for their authoritative treatment. Renton's brother Billy dies in Northern Ireland with the British Army. Renton attends the funeral; there, he almost starts a fight with some of his father's
Unionist relatives, and ends up having sex with Billy's pregnant girlfriend in the toilet.
Section 5: Exile Renton is stranded in London with no place to sleep. He tries to fall asleep in an all-night porno theatre, where he meets Gi, an old homosexual who lets him stay at his flat. Later, Renton, Spud, Begbie, Gav, Alison and others venture out for another drink and something to eat.
Section 6: Home Spud, Begbie, and a teenager engage in a robbery. Spud later comments on Begbie's paranoia and how the teenager is likely to get ripped off by the pair. Gav tells Renton the story of how Matty died of
toxoplasmosis after attempting to rekindle his relationship with his ex using a kitten. The group attends Matty's funeral. Later, Renton returns to Leith for Christmas and meets Begbie, who beats up an innocent man after having seen his alcoholic father in the disused
Leith Central railway station. He visits a former drug dealer, Johnny Swan, who has had his leg amputated as a result of heroin use, and he visits Tommy, who is dying of AIDS.
Section 7: Exit Renton, Sick Boy, Begbie, Spud and Second Prize go to London to engage in a heroin deal and see a
Pogues gig. Renton steals the cash and goes to
Amsterdam. Renton thinks that he will send Spud his cut, as he is the only 'innocent' party. ==Stage adaptation==
