A new, NSFW trailer for "T2 Trainspotting," the upcoming sequel to Danny Boyle's 1996 dark comedy "Trainspotting," is here, checking in with the first flick's protagonists two decades later.

The clip opens with Mark Renton (Ewan McGregor) returning to his Scottish hometown, where he tracks down his buddies Spud (Ewen Bremner), Sick Boy (Jonny Lee Miller), and Begbie (Robert Carlyle). While Mark seems to have more or less moved on from his drug-addled days that were depicted in the first flick, it seems his friends are more or less in the same place.

"So, what you been up to for 20 years?" Sick Boy asks Mark, seeming less than thrilled to see his old friend.

It seems Mark has spent much of that time reflecting on and distancing himself from his past -- he tries to make amends with his former flame, Diane (Kelly Macdonald), and promises her he's no longer a heroin addict -- though it doesn't take him long to fall back into some of his old habits. Still, he urges his friends to "choose life" over a life of drugs, saying in a rousing monologue, "You're an addict. So be addicted. Just be addicted to something else."

"T2 Trainspotting" hits U.K. theaters on January 27, 2017. It's due to debut in the U.S. for a limited run on March 3, 2017, with a wide release planned for March 10, 2017.
