ITV’s Unforgotten - when it’s back, how to watch series 5, entire cast, and plot

ITV drama Unforgotten is set to return for a fifth series and this time with award-winning actress Sinéad Keenan in a leading role. Each of the six episodes are written by show creator and executive producer Chris Lang.

The cold case murder drama originally aired on ITV in 2015 and centres around the Bishop Street unsolved crimes team. Usually, detectives Cassie Stuart and Sunil ‘Sunny’ Khan work together to tackle London’s most dismal crimes but the tragic departure of DCI Stuart means there will be a new lead stepping in to fill her shoes.
