Ackland and fiancee Rod Jessop work together when Valentine and Casper find a pupil from Harvey Wallace school, Martin Clarke, with stab wounds. Noble is frustrated when Hollis' stomach ache keeps him indoors looking at CCTV into the theft of bandages. Meanwhile, Gold and Smith attempt to locate a missing prisoner, Jimmy Collins. All three cases collide when it appears that Collins has a link to prime stabbing suspect Tom Ryan, while Hollis spots Collins on CCTV stealing bandages. Ackland stuns Jessop by suggesting early retirement.
