Spooks, A Chance for Peace

A British soldier is kidnapped by al-Qaeda, with the warning he will be killed unless Remembrance Day services are cancelled, and Harry is reunited with his protege.

Harry vows revenge on Kachimov following the explosion, but the government demands proof of Russian involvement. Lucas is desperate to return to the Grid.

Ben infiltrates an al-Qaeda cell planning a bombing campaign in London. Harry is concerned to learn the Russians may have a mole in the upper echelons of MI5.

Harry and Ros agree to meet an al-Qaeda terrorist leader, who is offering to exchange intelligence on a planned bombing in London for the pardoning of two prisoners.

Ros is sent undercover to investigate a businessman trying to undermine the British economy, but she is forced to use her powers of seduction when Lucas is recognised.

A teenager who witnessed a murder holds the key to an assassination plot. Lucas discovers the real threat comes from inside the security services.

Harry is arrested after being framed as the mole who revealed classified information. With Britain under renewed threat of nuclear attack, the whole team comes under suspicion.

Russian sleeper agents plan to detonate a nuclear bomb in London, prompting the team to kidnap the mole and force her to help prevent the attack.
