A world at war, many sparrows must fall, are the ominous words that open this classic 1943 film noir. That sparrow could be Kit McKittrick (John Garfield), a former Spanish Civil War prisoner who arrives back in New York to discover the truth behind the mysterious death of his friend Louie Lepetino. McKittrick is on the verge of near madness following the psychological torture inflicted on him whilst imprisoned in General Franco s civil war jails. Haunted by a sadistic man with a limp, McKittrick finds himself surrounded by Nazi spies who want to steal a precious artifact that he has brought with him following his escape from Spain. Around him there is only uncertainty with the sinister Dr. Skaas (Walter Slezak) who is fascinated by the effects of psychological torture; and Tonni Donne (Maureen O Hara), an elusive, elegant beauty who knows more then she s telling. As McKittrick tries to uncover a nest of Nazi spies whilst retaining his sanity, the stakes become higher in this excellent psychological thriller.
