This extraordinary episode opens with the dawn arrest of a man on suspicion of conspiracy to murder. The film documents the work of the lead detectives as they investigate and interview the suspect about his involvement in a plot to shoot a man. While driving to work, the victim was hit from behind by another vehicle. When he stepped out to inspect the damage he was shot in his leg by a close range sawn-off shotgun, sustaining life-threatening injuries. The police believe the case arises from a potential love triangle that has spiralled out of control. Detectives have 24 hours to gather enough evidence to charge or release him.

News spreads across the county about a suspected paedophile trying to abduct young children on their way home from school. Local press coverage has led to hundreds of calls from panicked parents to the police.

Following his second arrest, he makes a frank and shocking confession. The detectives take this new information to the Crown Prosecution Service in the hope of preventing him from committing any more offences.
