Laurence Rains (Stewart Granger) is annoyed when female architect Hilary Clarke (Rosamund John) insists he must enlarge the first aid room in his factory to satisfy government regulations, despite having the best safety record in the country. He encounters her once again, now a nurse trainee assisting a doctor treat one of his employees. He finds out that Clarke only became an architect to please her father, who had no sons to follow in his profession. When she saw how her young assistant at her firm, seriously injured in a traffic accident, was tended to by the nurses, she found her true vocation. Pamela Siddell (Margaret Vyner), a violinist and Rains' fiancee, sees his attraction to Clarke.
