Porno is a novel by Irvine Welsh. The novel is a sequel to Trainspotting. We rejoin the characters of that book a decade later, as their paths cross again in Leith, this time in the pornography business. They are joined by some of the cast of Glue. Sick boy from the first novel feels he is a failure in life. He has been married with children and is now divorced. Despite the fact that he thinks he is smarter than all around him he has yet to make it rich as he has always hoped. Some new chance encounters draw him to the conclusion that his only chance to make it big is to produce a pornographic film. To do so however he needs to regain contact with some friends from the first novel who he would rather forget about.
