London, 1954. Zina Pavlou, a Cypriot grandmother, waits quietly in the custody of the Metropolitan police. She can't speak their language, but she understands what their wary looks mean: she has been accused of the brutal murder of her daughter-in-law. Eva Georgiou, Greek interpreter for the Met, knows how it feels to be voiceless as an immigrant woman. While she works as Zina's translator, her obsession with the case deepens, and so too does her bond with the accused murderer. Zina can't speak for herself. She can't clear her own name. All she can do is wait for the world to decide.
