Episode 4

Sgt Tom Elvidge heads to Grimsby on the hunt for a prolific criminal who is linked to multiple burglaries, and is also known for not having a driving licence. Tom parks up to stake out the suspect, when suddenly he drives straight past him and the officer sets off in pursuit. In Hull, PC Billy Stead is riding out with new officer PC Megan Cetti when something catches his attention at a set of traffic lights, while PCs Luke Thundercliffe and Rich Stork respond to reports of a driver high on laughing gas in Grimsby.
