Alfred Day wanted his war. In its turmoil he found his proper purpose as the tail-gunner in a Lancaster bomber; he found the wild, dark fellowship of his crew, and - most extraordinary of all - he found Joyce, a woman to love. But that's all gone now - the war took it away. Maybe it took him, too. Now in 1949, employed as an extra in a war film that echoes his real experience, "Day" begins to recall what he would rather forget.
