The new season sees Nicola Walker (Last Tango In Halifax) and Sanjeev Bhaskar (Goodness Gracious Me) reprise their roles as DCI Cassie Stuart and DI Sunil “Sunny” Khan as they investigate another emotionally-charged cold case.

Set across the south of England in locations including Norfolk, West Sussex, Bristol, Hampshire and London, the new season explores how everyday lives can be fractured and destroyed by one event, showing that appearances can often be deceiving.
