It was a scandal that shook the British establishment to its roots. In June 1951, the government was forced to admit that two Foreign Office diplomats had disappeared. One of them, Donald Maclean, had slipped through their fingers three days before he was due to be questioned for passing secrets to the Russians. The other, Guy Burgess, was a total surprise. He was a charming, clever Etonian, with powerful friends everywhere. And lovers too - at a time when homosexuality was illegal, Burgess made no secret of his sexual tastes. He turned out to be the most flamboyant of a ring of privileged Cambridge students who had secretly joined the Communists in the 1930s, disgusted by their own government's policy of appeasing Hitler.

With the help of newly declassified documents, George Carey's film shows how the most celebrated spy ring of the 20th century grew out of the class system, sexual hypocrisy and the sheer incompetence of some people who then ran Britain.

After five years of war in Syria the remaining 350,000 citizens of Aleppo are constantly under siege. Through the eyes of the volunteers of the White Helmets, in this film we experience daily life and death in the streets of Aleppo.

Khalid, Subhi and Mahmoud are founding members of the White Helmets and are the first to enter destroyed buildings, scouring through the rubble in search of bodies and signs of life. They have chosen to stay in Aleppo to help save their people during the never-ending siege.

Many lives including those of countless children and infants are lost during the bombings. But each day is a dilemma and a conflict for the men - should they stay and risk death themselves, or should they try to get out and save their own families, as other have?

The film is a collaboration with the Aleppo Media Centre, and tells the extraordinary story of real heroes in an epic human tragedy.
