David Evans a dominant violent, ruthless and arrogant gangster has acquired his wealth by illegal drug trafficking. A killer without remorse. The success of his expanding criminal empire is dependent on imposing fear with swift and harsh punishment for betrayal. Few witnesses are prepared to cooperate with police. Those who do 'disappear' and are murdered.
The number of unsolved drug related murders increases. A dedicated police team of detectives is established to investigate Evans and his associates. He takes pleasure in mocking police efforts. It becomes evident he is receiving inside information from an unknown police source.
Three people are kidnapped. The location of their incarceration is not know. Intelligence states Evans has ordered they be murdered. In a race against time, and under the strictest secrecy without the knowledge of the police team, MI5 is tasked to infiltrate the organisation to save the three individuals and to gain evidence against Evans and his associates.
