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.
