Brownlow and Mannion attend the panel for a Metropolitan Police hearing against a Sergeant who is charged with disobeying a direct order, which resulted in the career-ending injury of another officer. Mannion is easily convinced of Sergeant Gartland's guilt, but Brownlow isn't so sure. When Ch. Insp. Caine struggles to explain the evidence presented against him, and corroborative evidence from Sergeant Tillman, who is based at another station, soon begins to sway the evidence in Gartland's favour. However, when the injured officer, PC Beckett, takes to the stand, her testimony sounds a little too much like she is trying to cover for Gartland's mistake, but Brownlow remains convinced of Gartland's innocence.

Meadows is furious when Chandler demands he replace Cullen as Senior Investigating Officer following the murder of Darren Freeley. Meadows is desperate to make the breakthrough as quickly as possible, aware that Chandler will be coming to his discipline board later in the week. Meadows questions the prime suspects, two friends of Melody Griffiths who were seen leaving the scene, KJ Leonard and Oz Benson. Traces of Leonard's skin are found on Darren Freeley's knuckles, and although Oz Benson admits they were there and were angry with Freeley, they didn't kill him. When Rickman finds the murder weapon, the forensic evidence points to an unlikely killer.
