Jim Broadbent stars as Tony Webster, the curmudgeonly divorced owner of a specialist camera shop in London. He still has a cordial relationship with his ex-wife, Margaret (Harriet Walter), and the two share a strong bond with their daughter, Michelle Dockery’s matter-of-fact Susie, who’s extremely pregnant and on the verge of having her first child on her own. The arrival of a registered letter disrupts his routine. It turns out that the mother of his first love, Veronica (played as a young woman by Freya Mavor, and as an older woman by Charlotte Rampling), a vivacious young woman he met in college, has died. She has willed him an item that Veronica, whom he hasn’t seen in over 50 years, now refuses to give him. As Tony tries to track it down, he shares with Margaret the story of this young romance, as well as the friendship with a fellow classmate that came to a tragic end.
