During the 1940s, Maurice Bendrix (Van Johnson), a writer recently discharged from the armed service, falls in love with Sarah Miles (Deborah Kerr), whom he interviews for a book. Sarah is married, but she and Maurice eventually give in to their mutual attraction, leading to an affair that lasts several months. Maurice's jealousy, along with the bombing of London by the Germans, seemingly lead to the end of their relationship. However, the reasons are later revealed to be more complex.
