Susan Traherne, a British woman whose life threads through the backdrop of World War II and its aftermath, begins as a determined courier whose work draws her into the secrecy and danger of resistance circuits. In 1943, she waits in the woods for a message to be dropped by parachute when Lazar Sam Neill parachutes down after aircraft trouble. They manage to slip away from German troops, and in the shelter of that tense night, Susan opens up emotionally to Lazar. They share a passionate night, but come morning he leaves abruptly after a warning he receives over his wireless to “move on.” Before he goes, he leaves her a pair of cufflinks as a bittersweet keepsake, a small memento of the connection they forged under pressure and peril.
Two years pass, and Susan’s path crosses with Tony Radley, whose sudden death from a heart attack draws Raymond Brock from the British Embassy into her orbit. He consoles her, and a complicated relationship quietly forms as Susan moves from a job as a clerk into a more public, comfortable life, living with her friend Alice. Susan and Raymond navigate the uneasy balance between romance and a pragmatic partnership, and she begins to test the edges of traditional happiness.
By 1953, Susan finds herself involved with the coronation committee for Queen Elizabeth, a role that exposes her to yet another layer of public life. She asks Alice’s former lover, Mick, to father her child, hoping to raise the child on her own terms. Her attempts to conceive are fraught and ultimately unsuccessful, and when Mick is hesitant, she presses forward, culminating in a confrontational moment where she fires a gun above his head. The episode underscores her growing restlessness and the fragility of the life she’s trying to sculpt.
After a brutal nervous breakdown, Raymond Brock visits her in the hospital, and the pair eventually marry. Yet the marriage cannot quiet the storm inside Susan, and the couple’s affluent, conventional life cannot fill the ache of her longing for something more. In 1956, a dinner party devolves into an embarrassing display of Susan’s erratic behavior, casting a pall over their social circle. Her husband’s employer, Sir Leonard Darwin, announces his resignation in the wake of the Suez Crisis, marking a turning point that foreshadows further upheaval.
Years later, the couple’s life takes them to Jordan, where Raymond holds a diplomatic post and Alice visits, sensing Susan’s subdued mood. Susan returns to England for Sir Leonard Darwin’s funeral, a move that enrages Raymond and intensifies the sense that her restlessness is pulling them apart. When she pushes back against Raymond’s stalled career in 1962, she confronts Sir Andrew Charleson, insisting that his path must change or face consequences. The confrontation leads to a dramatic decision: she threatens suicide unless Raymond is promoted, resulting in Sir Leonard Darwin’s forced dismissal and retirement from the post.
Back home, the battles between independence and partnership come to a head as Susan argues with Raymond and leaves when he is knocked unconscious. Her search for meaning continues as she rekindles her affair with Lazar, meeting him again at a seaside hotel. They share a final, intimate chapter, but Susan’s confession of mental instability arrives with the dawn; Lazar leaves, though not before noticing the cufflinks he’d given her years earlier, now returned to her as a quiet, haunting symbol of the years they spent apart and the person she remains.
In the closing memories, Susan recalls the idealism of youth in the French countryside after the war. She speaks with a local farmer and agrees to attend a party with his family to celebrate an uncertain peace, an ending that glints with irony as she proclaims—despite everything—that there will be many more days like this to come. The film traces one woman’s lifelong quest for significance against the heavy weight of history, ambition, and the intimate ache for connection that endures beyond even the most monumental upheavals.
