Boyden attends the scene of an RTA involving an HGV and discovers fridge/freezers with holes in bottom. Stamp and Quinnan come across a group of men wandering away from the crash, however only one is arrested. Upon his arrival to custody, he asks to speak to Conway, revealing he is an immigration officer from France and he was onboard the crashed truck with a group of immigrants.

Page and Quinnan pose as a married couple running a hotel, while Carver and Hollis, and immigration agent Petrit, pose as their employees. Stamp continues his undercover role as an HGV driver for the firm bringing in the illegals, while Webb, Lennox and McAllister maintain surveillance on the hotel. The hotel is busy preparing for its opening night, and when the temporary staff arrive, Quinnan seizes the opportunity to attract Berisha's attention by ringing the agency and complaining about them. Later, Stamp makes a delivery to the hotel – four refugees who are immediately set to work. He then picks up his boss Kerns and drives him to a lorry park, where he finds twenty scared refugees and a decomposing body.

The operation appears to be in jeopardy again when Petrit declares that he is going in search of his missing sister. Following a lead from a girl at a café, he and Carver visit a pool hall, but have no joy with the doorman. Page meets up with Cullen to give him an update, and tells him that she is convinced that they are being set up for extortion by Berisha. Her suspicions are later confirmed when Berisha presents Quinnan with a bill for excess staff. Initially, he refuses to pay, until Berisha starts to strangle him, watched by a helpless Webb and Lennox. A determined Petrit plans to return as a punter to the pool hall where his sister may be, which is identified as a brothel.
