Ailsa Jennings and her son Lyle Jennings are revealed as the kidnappers of Merritt Lingard, with Merritt being held in a hyperbaric chamber on an abandoned warehouse island.
Carl and Akram locate Merritt in the hyperbaric chamber and try to safely lower the pressure to avoid killing her. Lyle confronts them with a shotgun, shooting Carl in the shoulder. Akram fights back, kills Lyle, and they successfully rescue Merritt.
Ailsa Jennings attempts to escape by ferry but is blocked by police. Rather than be arrested, she shoots herself in the head before the police can intervene.
The 999 call was traced back to Ailsa Jennings' phone, which raised suspicion. Constable Cunningham, who investigated the call, found Merritt in the hyperbaric chamber and confronted Lyle Jennings, leading to a violent encounter.
During the rescue, Carl is shot in the shoulder while protecting Akram, who remains uninjured. Akram then kills Lyle, saving both Carl and Merritt. This act contrasts with earlier tensions, showing Akram's heroism and Carl's protective instincts.
