Heroin addict Mark Renton stumbles through bad ideas and sobriety attempts with his unreliable friends -- Sick Boy, Begbie, Spud and Tommy. He also has an underage girlfriend, Diane, along for the ride. After cleaning up and moving from Edinburgh to London, Mark finds he can't escape the life he left behind when Begbie shows up at his front door on the lam, and a scheming Sick Boy follows.

Hubert, a brash 17-year-old, is confused and torn by a love-hate relationship with his mother that consumes him more and more each day. After distressing ordeals and tragic episodes, Hubert will find his mother on the banks of Saint Lawrence river, where he grew up, and where a murder will be committed: the murder of childhood.
