The story follows Hortense Cumberbatch, a capable optometrist, who seeks her birth mother after her adoptive mother's death and learns it is Cynthia Purley, a white working-class woman. The interracial adoption surfaces as an initial shock in early scenes, including Cynthia's denial upon meeting Hortense, yet the film quickly shifts focus to individual bonding, class tensions within the Purley family, infertility struggles, affairs, and resentments that erupt during a birthday party gathering.

This approach keeps the interracial element as one driver among many personal secrets instead of a platform for broader social commentary. Director Mike Leigh framed the project around adoption experiences, roots, and identity, with the explicit goal of depicting capable young black professionals beyond stereotypes and emphasizing connections between people as individuals. Produced in 1996, the film contains no lecture-style moments, systemic critiques, or identity-politics framing. The diversity arises organically from the adoption premise without altering source material or injecting contemporary activist elements, resulting in a traditional British family drama that prioritizes character-driven catharsis over messaging.
