In Episode 7, a video sent by reporter Dennis Piper shows a 17-year-old Sam Haig talking about viciously assaulting another boy who kept following him, believing he was his brother. It is also revealed that Sam had slept with Chloe, the wife of Paul Evans, the night before Sam's death, and that Sam was staying at The Spivey Inn, not the Prince’s Garden hotel where Merritt used her credit card. These details deepen the understanding of Sam's troubled past and connections to other characters.

Carl Morck and Akram discover that Merritt Lingard and Sam Haig were working on exposing corruption involving Graham Finch and Kirsty Atkins. Kirsty was supposed to testify about meeting Finch’s wife at a women’s refuge, but Stephen Burns had blocked her testimony. After Kirsty was attacked for talking to Merritt, Carl suspects Finch had insiders protecting him. Merritt’s disappearance and her connection to these events are central to the episode’s plot.

Stephen Burns is confronted by Carl and Akram about his knowledge of the connections between Merritt, Sam, Kirsty, and Liam Taylor. He denies recalling key details, including Kirsty’s attack and the corruption allegations. However, Akram catches him in inconsistencies, especially regarding Kirsty’s addiction. Stephen’s reluctance and evasiveness raise suspicions about his involvement or knowledge of the cover-up.

During her captivity, Merritt attempts to escape by dialing 999 from an old lady’s phone. However, her male captor interrupts and stops her before she can get help. This tense moment highlights Merritt’s desperation and the danger she is in while held in a hyperbaric chamber.

Through flashbacks, it is revealed that Merritt had a close childhood relationship with Harry Jennings; they used to smoke together and were romantically involved. This background adds depth to Merritt’s character and explains some of her rebellious behavior. Jamie, another character, is unhappy about these ties but is powerless to intervene because Merritt is independent and does not listen to advice.
