Unforgotten 2021 trailer and start date for season 4 revealed

Unforgotten starring Nicola Walker and Sanjeev Bhaskar is back on ITV for a fourth series.

BAFTA nominated actors Nicola Walker (Last Tango In Halifax, The Split) and Sanjeev Bhaskar (Yesterday, Goodness Gracious Me) reprise their roles as DCI Cassie Stuart and DI Sunny Khan.

The new six-part series charts a fresh investigation into another emotionally-charged cold case murder.

The opening episode begins with the discovery of a dismembered body in a scrap metal yard, which the team believe has been stored in a domestic freezer for thirty years. Various clues lead to the victim being identified as Matthew Walsh, a young man in his mid-twenties who went missing in March 1990.

Unforgotten series 4 starts Monday, 22 February at 9PM on ITV.

Writer Chris Lang said: “I am so excited to be bringing back the Unforgotten team for a fourth series, as Cassie and Sunny take on perhaps their most challenging case to date. Once again, we have assembled an astonishing cast, and I cannot wait to see how the very finest actors of their generation, start bringing my characters to life.”

Unforgotten first debuted on ITV in 2015 and has gone on to prove a hit.
