The Bay series 4 plot details and the cast for the returning crime drama have been revealed by ITV.

A fourth run for the Morecambe-based thriller was confirmed as the third series came to an end back in February.

It starred Marsha Thomason as rookie Family Liaison Officer DS Jenn Townsend. Knowing Marsha is back for the fourth series will no doubt delight fans.

She took over the lead role from Morven Christie, who played DS Lisa Armstrong in the first and second series.

So what will happen in The Bay series 4 and who’s in it?

The Bay series 4: What’s the plot?

Announcing that filming has begun, ITV gave a very broad tease for series 4’s storylines.

Morecambe’s MIU team are called on once again. This time a young mum-of-four, Beth Metcalf, dies in what appears to be a targeted attack.

DS Jenn Townsend immediately realises Beth’s shattered family will need all support available to them.

Beth’s bereft husband Dean finds himself numb from shock. He feels completely unprepared to be the sole carer for his four kids.

Struggling at every turn, Dean cannot process what’s happened to his wife and his family.

But as DS Townsend, DI Tony Manning (played by Daniel Ryan) and the team dig deeper, they uncover secrets at every turn.

We can’t wait!
