THE LADYKILLERS showcases Alec Guinness in one of his most unforgettable performances as Professor Marcus, mastermind of a gang of vicious bank robbers who rent a room from an elderly widow. But when the dear old woman begins to meddle in their "perfect crime," the crooks decide that she might pose the biggest threat of all.

In the British manufacturing country of Northern England, factory owner Michael Corland (Michael Gough) is showing competitor Alan Bimley (Cecil Parker) around his plant, hoping to borrow some money and marry off his daughter Daphne (Joan Greenwood). They come upon a curious contraption that turns out to be an experiment by employee Sidney Stratton (Alec Guinness). Being a lower class worker, Sidney is summarily fired from his job. Sidney ends up working at Bimley's factory, where he is befriended by militant worker Bertha (Vida Hope). Daphne spots Sidney at the factory and he explains to her the results of his experiment -- a material that is indestructible and impervious to dirt. Bimley discovers this project and throws Sidney out. But Daphne, impressed by his experiments, funds Sidney, installing him in his own laboratory. After a few false starts, Sidney develops a pure white material that can't be dirtied or ruined. But it seems Sidney's invention is too brilliant and effective; if a material is marketed that will last forever, textile mills will go out of business and workers will lose their jobs. Suddenly, poor, luckless Sidney has both management and labor banding together to combat his new invention.

Sidney Stratton (Alec Guinness) invents an indestructible cloth that never gets dirty and celebrates by having a white suit made of the fabric. But soon, the lowly mill workers start fearing for their jobs while the mill owners worry about their profits. Chase scenes and double-crosses ensue as the impish Stratton struggles to defend his discovery from the mob. Ernest Thesiger portrays decrepit mill owner Sir John Kierlaw.
