The six-part series is based on the hit Swedish thriller of the same name, with the UK adaptation taking place in Bristol.

Before We Die follows detective Hannah Laing (Lesley Sharpe) who discovers her son is playing a crucial role in a brutal murder investigation as an undercover informant.

Patrick Gibson (The OA) stars as Christian, Hannah’s mixed-up son whose role is causing deep conflict for his mother.

Vincent Regan (Wallander) plays Billy Murdoch, an unconventional investigator seconded to advise on Eastern European drug gangs in Hannah’s unit.

Together the pair attempt to track down criminal king pin Davor Mimica, played by Croatian actor Toni Gojanović.

Caroline Hollick, Channel 4’s Head of Drama who commissioned the series, commented: “Every episode of Before We Die is a roller coaster of excitement – and I’m so delighted to have Lesley Sharp bring her trademark gravitas and charisma to Channel 4. It’s a privilege to be part of this truly inspiring European collaboration.”
