This film looks at the Civil Defence Corps as volunteers go through a training exercise involving rescue and background operations such as communications rooms. The film opens with shots of a model of Sunderland (?) where streets are made to look as though hit by a major catastrophe. The remains of buildings and rubble fill the streets. Members of the Civil Defence Ambulance Corps look on as an officer points to significant areas on the model. A map of Sunderland shows areas which have been given operational numbers. A high angle view follows as Civil Defence arrive by lorry at a make-believe disaster site where personnel will carry out training in derelict buildings and demolition rubble, presumably in the Sunderland area. Reserves wearing protective equipment carry out tasks such as sifting through rubble to rescue an injured man. The man is placed on a stretcher, as another stretcher case passes by. Nearby 'derelict' buildings are examined for casualties. An injured woman is strapped to a stretcher and carefully lowered down a ladder. A more elaborate rescue from the top of the building requires scaffolding an ropes and pulleys to lower the victim to ground level. The casualties are taken to nearby ambulances. "Defence Corps, Sunderland Division, Ambulance and First Aid Section' is printed on the side of an ambulance.  A reserve checks those casualties who are put into the ambulance, and enters information onto a sheet attched to a clipboard. A female member of the team gets out of the ambulance and another casualty is placed in the vehicle. The doors are closed and it moves off. The scene changes to an operations room where information is being placed on a wall size plan or map. Radio or wireless telephone operators note down information onto a special form. Outside, a group of men pore over a plan. One man uses a radio telephone which is strapped to his back. Tthe film cuts to a vehicle trailer which has a cable drum on it. The cable is played out by a group of men. Back in the operations room, and a communications room, booths are equipped with telephones operated by Civil Defence personnel. A resume of some of the rescue scenes seen earlier are repeated. A 3D model seen at the beginning ends the film showing again destroyed streets amidst piles of rubble.
