Luther: The Fallen Sun

In London, Callum Aldrich is a young man that receives instructions by phone to go to an isolated road. He sees an accident, reports to the police and is kidnapped by a stranger. Detective John Luther is in charge of the investigation and promises Callum's mother, Corinne Aldrich, that he will find her son. However, the kidnapper David Robey, asks someone to find evidence that Luther is a dirty cop. He is arrested and sent of a maximum security prison, and Robey kills and burns Callum and other victims in a house. Luther talks to a contact to break out the prison to catch the killer. But the incompetent chief of police Odette Raine makes his hunting of the psychopath more difficult chasing him, especially because there is a mole that works for Robey at the police station.
