A 1945 British film directed by David Lean
, written by NoŽl Coward
and starring Celia Johnson (who got a Best Actress nomination) and Trevor Howard.
Laura is a suburban housewife in a rather dull marriage; one day, while waiting in the refreshment room of a train station, a doctor called Alec helps her remove some grit from her eye. He is also married, but over time the two of them strike up a friendship, which blossoms into something more. But this being middle-class suburban Britain in the 1940s, they cannot possibly be together; Alec is called away for medical work in South Africa, and the two lovers are parted.
The story is told In Medias Res
from Laura's point of view after the pair separate as she travels home
