The film follows the daily working life of the stretcher and rescue parties at the ARP depot in Fulham. The men's day begins at 6am and ends at 10pm. In between these hours they undertake a range of routines aimed at keeping them prepared for any emergency callouts. Under the guidance of the Superintendent and the party Leaders, the men ensure that their dormitories are clean, that their vehicles are roadworthy, and that their equipment is ordered and ready for immediate use. The men are also inspected by their superiors and schooled in the art of stretchering the injured away from dangerous situations (including a bombed building). They partake in physical exercise, eat their meals in the canteen, and relax in the recreation room. The extensive training and drills ensure that the parties respond in an efficient, calm and ordered manner when a call comes into the depot in the late afternoon. The men return to the depot from the incident for a debrief, where they utilize the recreation room before lights out at 10pm.
