DI Ray is set in Birmingham and follows Leicester-born Rachita Ray, a police officer who takes on a case that forces her to confront a lifelong personal conflict between her British identity and her South Asian heritage.
Following the discovery of the missing gun, DI Ray's lens turns back to the Chapman family. Suzie takes drastic action, and DI Ray and Clive enact their risky plan to expose corruption in the highest ranks of the force.
