THEY FIGHT BY NIGHT [Main Title]

An impression of the many ways the war effort is carried on round the clock: "night no longer means rest for Great Britain".

The work of many people continues, or only begins, after the conventional working day: brief shots recall the activities of nightfighter pilot (at standby); Observer Corps; Coastal and AA guns; fire guards at office building; National Fire Service; air raid wardens; Home Guard (a grocer shuts up shop and leaves for duty); factory night shift; bomber crews (take off); lorry drivers; farm workers (night ploughing); searchlight and sound detector units (a woman crew; an alert; AA gunfire, nightfighter); iron/steel foundry night shift; soldiers on night exercise; (midnight: factory canteen); coal miners; new shift, shipyards; (bomber crews, return); merchant shipping convoys; railways. Dawn breaks: day workers get up (land girl, bus conductress), day shift clocks on; the Home Guard returns to his grocery. The battle "will know no pause this side of victory".
