The Keeper tells the incredible true story of Bert Trautmann (David Kross), a German soldier and prisoner of war who, against a backdrop of British post-war protest and prejudice, secures the position of Goalkeeper at Manchester City, and in doing so becomes a footballing icon. Struggling for acceptance by those who dismiss him as the enemy, Bert s love for Margaret (Freya Mavor), an Englishwoman, carries him through and he wins over even his harshest opponents by winning the 1956 FA Cup Final, playing on with a broken neck to secure victory. But fate will soon twist the knife for Bert and Margaret, when their love and loyalty to each other is put to the ultimate test.
