Antonia Bird's latest project is this visceral two-hour drama portraying the harsh realities of life in a drug-rehabilitation centre, as seen through the eyes of a petty criminal. Its subject matter and uncompromising style mean this film is particularly given to strong language, scenes of drug abuse and depictions of sex which some might find disturbing.

In the first part, Adam Bishop adapts to a new routine as tensions among his fellow residents begin to spiral. Then a visit to central London throws their fight with addiction into stark relief.Â

Concludes after Newsnight.
