A terror attack on a gas and oil depot has led to energy rationing and people dying of cold. One media group in particular is pedaling anti-government propaganda.
Amid rumors of further terror threats, the team discovers that intelligence about the terror attack was ignored by MI6.

Despite being confronted by MI5, the conspirators have already set in motion a chain of attacks, including a mid-air plane collision over London. But will the team avert the attacks in time?
