Curmudgeonly Briton "Howard" (Monty Woolley) is doing his best impersonation of "Rudolf Rassendyl", fishing peaceably and minding his own business, when the Nazis decide to invade France. He has to get home and is persuaded to take the two "Cavanaugh" children to safety with him. There's "Ronnie" (Roddy McDowall) and his sister "Sheila" (Peggy Ann Garner) who manage to irritate their new guardian just by being there, but they are just the start of his problems as they act like a magnet for other endangered children. Before he knows it, it's like he has his own herd of cats to try and smuggle out from under the nose of the menacing "Maj. Diessen" (Otto Preminger). Terrified of being heard to speak English, he and his charges gradually learn a little about themselves and this erstwhile selfish gent starts to demonstrate an whole new set of human traits hitherto a mystery to himself. Can he manage to get them, and himself, to safety though? It's a showcase for an on-form Woolley that features a few brief appearances from Anne Baxter and J. Carrol Naish as the adventure builds slowly but quite menacingly to a denouement that has something of last year's "Pimpernel Smith" to it. McDowall's is an engaging young character and the story exudes quite a healthy degree of sentiment-free mischievous charm as Woolley delivers the goods once again.
