Spooks: The Seventh Division: Screenplay

Eight Customs & Excise officers are killed by the Chala, a ruthless Colombian cartel led by Rafa Morrientes, who is in England to meet with powerful businessman Ross Vaughan. Tom and Zoe go undercover to befriend Mariela Hernandez, Rafa's girlfriend, while Danny spies on Rafa's meetings. There, Section D learns that Rafa is trading cocaine for surface-to-air missiles with Vaughan's help. Meanwhile, Sam unknowingly spies on the team for former officer Tessa Phillips, who was fired for running phantom agents for monetary gain, under the guise that she is Harry's superior. Tessa offers to supply the team with information needed to stop Rafa from her Spanish contacts. However, Harry decides to suspend her contacts. After Tom and Zoe turn Mariela to seduce Vaughan for information, Tessa exposes Mariela's treachery to Rafa, who murders her. After the deal for the missiles is intercepted, an unidentified party kills Rafa, while Tessa flees the country to escape Harry's reprisal. Tom is disgusted to hear from Harry that they will not pursue Vaughan any further, placing the two at further odds. Tom continues to see Christine behind Harry's back.
