The Bay is heading back to ITV soon, with the broadcaster confirming the news that the popular crime drama has started filming the next installment.

Once again, the series is filming in Morecambe and will see Marsha Thomason (White Collar) reprising her role as Morecambe CID’s Family Liaison Officer, DS Jenn Townsend.

Series regulars Daniel Ryan (Innocent) Erin Shanagher (Peaky Blinders), Thomas Law (The World’s End) and Andrew Dowbiggin (Coronation Street) also return alongside Marsha, as well as Barry Sloane (Revenge), Georgia Scholes (Hollyoaks), David Carpenter and Emme Haynes.

ITV has also released plot details for The Bay season 4, which are: "When young mum of four, Beth Metcalf, dies in what seems to be a targeted attack, Morecambe’s MIU team are called to the scene. Jenn immediately realises this shattered family will need every support available to them.  

It adds: "Bereft husband Dean finds himself at sea. Numb from shock and completely unprepared for being the sole carer to his four children he struggles at every turn - unable to process what’s happened."
