A third season of investigations and emotional roller coasters in “Unforgotten” airs Sundays at 9 p.m., April 7 – May 12 on Arizona PBS.
Set in the southern part of England, this season’s case involves a missing 16-year-old girl whose body is found near a London motorway. The police investigation failed, and detectives Cassie Stuart and Sunil “Sunny” Khan are determined to find the truth.
Nicola Walker and Sanjeev Bhaskar reprise their respective roles as detectives Stuart and Khan. The pair are joined this season by four close-knit school friends who hold the key to what happened to the teenager: doctor Tim Finch, television host James Hollis, failing salesman Pete Carr and artist Chris Lowe. As the four suspects find themselves under the spotlight, their tight bond is put to the test. They all have secrets in their past and events that pulled their lives apart. None of them are quite who they first seem, but is someone capable of murder?
