So far, three seasons of The Bay have aired, and many viewers want to know if a fourth season is coming. We're happy to confirm that YES – The Bay has been renewed for season 4.

What's The Bay About?

The Bay is a British crime drama series produced for ITV. Set in the Morecambe Bay area, the show follows a family liaison officer (FLO) who works with the police to help grieving families in the aftermath of serious crimes.

In the first two seasons, we follow DS Lisa Armstrong (Morven Christie, Grantchester) – a troubled, middle-aged single mother who struggles to keep her personal and professional lives balanced. Unfortunately, acts taken in her personal life lead to hard decisions at work…and when she makes the wrong choices about how to handle it, she suffers some serious setbacks.

By season 3, most of the cast had changed. Marsha Thomason (Cobra) plays DS Jenn Townsend, replacing Morven Christie as the series lead. On her first day on the job, a body is found in the bay…and it only gets more complicated from there.

Tonally, The Bay is a bit like a less-funny Broadchurch without the star power of David Tennant, Olivia Colman, and Jodie Whittaker. It's on the darker side of things, and that pairs well with the gloomy, often gray landscapes of the region.

If you prefer shows like Agatha Raisin or Shakespeare & Hathaway, you may find it a bit too dark and dreary for your tastes. On the other hand, if you like shows like Vera, The Long Call, Shetland, DCI Banks, The Tower, and London Kills, you should definitely give it a try.

What's Happening in Season 4 of The Bay?

The Bay premiered in 2019 with Morven Christie (Grantchester) starring as DS Lisa Armstrong – A family liaison officer dealing with problems at home and work. Each season focuses on one case, but there are ongoing storylines at times.

Morven Christie played DS Lisa Armstrong for The Bay seasons 1 and 2. She left at the end of season 2, and Marsha Thomason (Pie in the Sky) became the new family liaison officer – DS Jenn Townsend.

In The Bay season 3, DS Jenn Townsend (Marsha Thomason) doesn’t have much time to adjust to her new surroundings before a dead body is found. Townsend works on the case of aspiring local boxer Saif Rahman who died under suspicious circumstances.

We had the chance to talk with Marsha Thomason before season 3 of The Bay Premiered. You can read that interview here.

In season 4, the mystery will revolve around the suspicious death of local mum Beth Metcalf. The team will need to get answers fast, as widower Dean is struggling to come to terms with the events and it's impacting his ability to care for their four children.
