Traitors premieres

A tense thriller set within the post-war corridors of power.

It is the story of the oddly-named Feef Symonds who is a bold young woman who joins the Civil Service in 1945 just as Clement Attlee’s Labour Party sweeps to victory, defeating wartime leader Winston Churchill in a surprise landslide.

Ambitious and determined to make something of her life, Feef is unappreciated by her family – but her American lover is a different matter. With his encouragement, she agrees to spy on her own government on behalf of the Americans, who have a hidden agenda: they want to ensure that England’s ‘socialist’ leaders don’t play into Soviet hands.

New on Channel 4.
