With insufficient forensic evidence to charge him, DI Neil Manson and DS Samantha Nixon have 24 hours to extract a confession from serial rape suspect Alan Kennedy. CPS laywer Jonathan Fox, who previously defended Kennedy on an assault charge, watches the proceedings with great interest, but the stress may be too much for him, and he jeopardises his relationship with Insp. Gina Gold when he makes a comment about her not having children. With police scouring Kennedy's mother's flat for forensic evidence or clues which will help, Manson and Nixon continue their interview, but Kennedy is a tough nut to crack. The next day, literally at the last minute, Nixon puts the pieces together and Kennedy finally confesses. Simultaneously, Dr Hugh Wallis finds a knife in the flat. With Kennedy behind bars, the relief attend a community party organised by Supt. Okaro, but the fun is quickly over when a massive bomb explodes.
