Tension, drama and comical mishaps abound as Brownlow, Meadows and Conway head to the Yorkshire Moors for an orientation course alongside the top brass from Barton Street. The tension builds as Conway backs out of the rock climbing due to his fear of heights, and Meadows is reprimanded by the instructor for both abandoning Conway to complete the test alone and his continual attempts to contact Daly as he tries to keep abreast of the investigation into an armed robber, who has stunned CID by suddenly handing himself into custody. Meanwhile, Brownlow clashes with his Barton Street counterpart Guy Mannion, a fast-track young go-getter who is prime candidate to rival Brownlow for the Borough Commander post. As the teams are tasked with crossing the Moors, Meadows plots an escape, but they unite in their determination to beat the Barton Street contingent after discovering they have used the Stafford Row team's knowledge of the course to give them an edge.
