However, throughout the show, boundaries between personal and private lives begin to blur and the drama begins to unfold outside of the criminal cases that are being investigated.
The Bay kicked off its third season on Wednesday, January 12 at 9pm.
Here is everything you need to know about The Bay season 3:
What happened in episode one?
It was confirmed in February that Morven Christie, who played DS Lisa Armstrong in The Bay, would be departing from the series.
Following her exit from the show, ITV announced that Marsha Thomason would be joining the crime drama as new family liaison officer DS Jenn Townsend.
In episode one, Jenn is involved in a car crash as she is on her way to drop her children off at school.
Immediately after this incident, the new officer is thrown into the deep end on her first day of the job when a body washes up in the bay.
The body in the bay is confirmed as Saif Rahman's (played by Brahmdeo Ramana).
Jenn then partners up with DS Karen Hobson (played by Erin Shanagher) to support the Rahman family as they begin to unravel who murdered the young boxer.
Saif was involved in a fight outside a new nightclub in Morecombe after a group of men harassed him and his girlfriend.
Saif's post-mortem revealed that he has been beaten with a blunt object, such as a baseball bat, and the club's CCTV showed Jordan Rooney (played by Conor Lowson) amongst the group of men.
They then raid Jordan's flat and bring him to the station for questioning but at the flat, they discover a baseball bat.
