Final episode. With Roach’s identity finally revealed, and the villain seemingly within the Unit’s grasp, the team now face the challenge of intercepting his massive shipment of drugs - and even more crucially, somehow linking it to him. Meanwhile, Roach (Trevor Eve) is feeling under pressure from both outside and inside his organisation, and becomes convinced that there is a traitor within his own gang. But what is he prepared to do to restore order in the ranks? As the Unit close in on what they believe to be Roach’s shipment, little do they know that Roach has a final surprise up his sleeve.
The Day They Dropped The Bomb
This new documentary marks the 70th anniversary of the world’s first atomic bomb which fell on the Japanese city of Hiroshima on August 6, 1945. The film provides a minute-by-minute account of what happened on that day, told by the last surviving member of the flight crew of the Enola Gay plane which dropped the bomb, navigator Dutch Van Kirk, in his final TV interview before he died. The Day They Dropped The Bomb was made by award-winning film-maker Leslie Woodhead, who directed the documentaries The Day Kennedy Died and 9/11: The Day That Changed The World, also for ITV.
