Returning: Unforgotten

UK crime drama Unforgotten returns for its fourth season on ABC later this month.

Nicola Walker returns as DCI Cassie Stuart and Sanjeev Bhaska as DI Sunny Kahn investigating a cold case with alarming links to the police force.

Unforgotten is a BAFTA winning drama, recently nominated the Royal Television Society Programme Awards, which screened in Britain last month.

A corpse is discovered in a huge scrap yard, buried among mountains of metal. The man’s body has been frozen for some time, and details about his life and death are near-impossible to make out. How long ago did this man die? And did the truth die with him?

With Cassie and Sunny on the case, four murder suspects quickly emerge. The suspects have just one thing in common: they’ve all got connections with the law. As the clues slowly emerge, it turns out all four suspects attended the same police training course back in 1989. Since then, their lives have gone in very different directions.

The volatile chief superintendent with a point to prove and a past to forget. A seemingly successful businessman with a criminal past. A Cambridge-educated high-flying cop in a toxic relationship with her mother. And the daughter of a policing family, pushed into a career she cannot stand. With all these links to the law, who exactly is fighting for justice?

Can the police force ever be trusted? And will Cassie and Sunny, both with troubles of their own, find themselves fighting on the wrong side of the law?

8.30pm Saturday 19 March on ABC.
