Ackland and Valentine attend a road traffic accident involving a disturbed young woman who has little recollection of wandering into the road. Later, they are called to the scene of an assault and find the woman attacking a bailiff who is attempting to repossess her car. Valentine is less than sympathetic to the accused, until they later find the woman atop a derelict multi-story car park, threatening to jump. Meanwhile, Manson leads the investigation into the assault on drug dealer Louis Drake, but when he identifies Nadir as his attacker, Nadir is forced to fake an alibi and an investigation report in an attempt to cover his tracks, but Manson isn't entirely convinced of his innocence.
