Taken On Trust is the 781st episode of The Bill. An unexploded wartime bomb is discovered on the riverside, in the middle of a surveillance operation. Insp. Monroe puts his contingency plan into operation, but he experiences some difficulty in convincing the locals of the danger they are in. As the evacuation gets underway, a group of squatters refuse to leave, thinking it's an attempt to evict them. Monroe eventually persuades them that threat is geniune, but D.S. Pearce and D.C. Carver slip into the squat and discover the drugs concealed there.
