The film revolves around Hortense Cumberbatch (played by Marianne Jean-Baptiste), a successful black optometrist in London who was adopted at birth. After the death of her adoptive mother, Hortense decides to search for her birth mother. She discovers that her birth mother is Cynthia Rose Purley (played by Brenda Blethyn), a working-class white woman who works as a factory worker and lives in a council flat.
When Cynthia and Hortense meet for the first time, Cynthia is shocked to learn that her daughter is black. Despite initial awkwardness, the two women form a bond and begin to explore their complicated family history. As they delve deeper into their past, they uncover long-buried secrets and painful truths about their family.
Meanwhile, Cynthia’s brother, Maurice Purley (played by Timothy Spall), is struggling in his marriage to his wife, Monica (played by Phyllis Logan). Their relationship is strained, and Maurice feels increasingly disconnected from his wife and daughter.
In the climax of the film, the family’s secrets come to a head during a tense and emotional confrontation at a family barbecue. Cynthia reveals the truth about her past and the circumstances that led to her giving up Hortense for adoption.

Maurice and Monica also begin to mend their fractured relationship, finding solace in their shared experiences and the love they have for each other.
