FROM THE CREATOR OF LINE OF DUTY AND BODYGUARD

Explosives Officer Lana Washington (Vicky McClure) is the first on call when an explosion in the heart of London signals the start of a deadly terror campaign across the capital. Newly back from secondment, she returns to her role as Senior Expo for the Metropolitan Police, working alongside Danny (Eric Shango), her assistant, John (Kris Hitchen), and Hass (Nabil Elouahabi), who’s been leading the team in her absence. When an investigation is launched to track down the perpetrators of a sophisticated and deadly attack on a power station, Lana is called upon for her expertise by the Met’s Counter Terror team, putting her back in a close working relationship with her ex-partner, DCI Thom Youngblood (Mark Stanley), his new partner, DS Helen Morgan (Natalie Simpson), DI Amir Batra (Maanuv Thiara), and new boss, Commander John Francis (Julian Ovenden).
