Women on the factory floor? An engineer needs convincing that war work is a feminine pursuit.

This propaganda film uses comic actor Alastair Sim to help recruit women into war work. With men away fighting, the crisis in weapons production meant that women were drafted in to take their places. But many women were put off by the idea of factory work and films such as this one tried to convince them that they could help their country by playing a key role in the war effort.

Dramatised sketch showing how women can train for engineering work in wartime.
Managing Director McForrest refuses to believe that women can do engineering jobs. His daughter wagers that she can complete a three-month training in two months, and hold an engineering post for at least a week. McForrest agrees that, if she is successful, he will employ women in his works. Mary trains at the Beaufoy Institute - shots of theoretical classes and practical work, the canteen, course schedule. Shots of Mary using a lathe; filing a piece of metal to exact measurements. McForrest receives the piece of metal anonymously through the post. Shots of Mary using drills and cutting tools. She makes more complicated test shapes. McForrest receives a parcel of them. Shots of Mary setting up her own machinery. McForrest gloats to his wife that he has won his bet, Mary must have failed the course. At his factory he finds that Mary has been working there for 10 days and, seeing a sample of her work, agrees to start employing women. Slogan stresses the need for women to work in industry and encourage more to do so.
