"T2 Trainspotting" picks up where the original left off, with Mark Renton (Ewan McGregor) returning to Edinburgh after a self-imposed exile in Amsterdam. The story jumps forward in time, with the characters now facing middle age, their youthful antics and excesses now tempered by the harsh realities of adulthood. Mark, Sick Boy (Jonny Lee Miller), Spud (Ewen Bremner), and Begbie (Robert Carlyle) are all struggling to come to terms with their own mortality, as well as the changing world around them.
