Airing tonight in the UK at 9pm on Channel 4 is the seventh episode of The Event entitled I Know Who You Are. The synopsis and trailer are below.

President Martinez orders Director of National Intelligence, Blake Sterling, to root out the mole from their staff, which causes Sterling to question his judgment of people close to him. Sophia reasserts her power over Thomas and the other detainees, and she prepares them for the next leg of their mission. Elsewhere, with the aid of Madeline, Sean continues his hunt for answers, all the while trying to stay one step ahead of the covert agents who trail him.
