Dakar, Senegal, 1987: On a rainy night after a wild party, the British ambassador's wife, Vivienne Hughes, is involved in a car crash. Her vehicle hits the motor-bike of a young Senegalese doc-tor, Aime Tunkara, killing him. Pleading diplomatic immunity, Vivienne and her husband flee to England.

Three decades later, Aime's little sister, Lily Tunkara, now a high-flying lawyer in Dakar, finds a photograph that compels her to investigate what really happened that rainy night. As Lily faces in-creasing hostility from the local community, she turns to Vivienne Hughes, the only remaining wit-ness, but is either woman pre-pared for the truth to emerge?
