BBC One is to broadcast a one-off Christmas special for Irish comedy hit The Young Offenders.

It's Christmas week, and the residents of the estate where Conor (Alex Murphy), Jock (Chris Walley) and Mairead (Hilary Rose) live have been fighting off an eviction from the council for over a month. The residents have created a barricade to show their determination that they won't be moved to make way for the estate to be renovated, afraid that they might never get back into their homes if forced out. The situation has been getting national media coverage and everyone involved is on edge, including the police.

While all this is happening, Mairead has been sick for weeks and has to be taken to hospital - a place Conor and Jock hate. The situation proves to be more serious than thought, causing major concern for the lads. Not knowing how to help, the lads ask Mairead if there's anything they can get her. Mairead says she's never seen a white Christmas, so the two friends set off on a chaotic adventure to try make her wish come true, which involves some accidental interaction with a local film crew - and a movie star – who ends up getting involved. When Billy Murphy (Shane Casey) enters the fray, all hell breaks loose. But the lads are determined to do something for Mairead, and in the process find out something about themselves and the value of empathy.
