A drab London boarding-house in the early ’50s. A woman gazes bleakly out of an upstairs window, her farewell message to her lover echoing through her mind – then closes the curtains, gulps a handful of pills, turns on the gas-tap and lies down to die.

A whirl of flashbacks take us through the backstory – her marriage to a dull elderly judge, her meeting with a dashing younger man and their impulsive affair that led her to this seedy room, while Samuel Barber’s Violin Concerto yearns achingly on the soundtrack.
