The Africa-holiday the McKenna family ends dramatically when a dying secret agent the father whispers pointing to a planned attack in England. To bring the couple silenced, the criminals kidnap the son of McKenna. First, helpless and frightened parents take on their own but the chase and get the plot on the track. With their knowledge they might prevent the crime, but then they would put their child's life on's game. Atmospheric dense enough playing well - a great Hitchcock classic. Although James Stewards acting performances were certainly not been exhausted in this film, he fills the role perfectly credible from, as well as Doris Day, which once embodied one of her rare serious roles here. The couple goes perfectly. Pieces of the tension builds up in the action and adheres to the end. Especially these days (the time it mutate in the normal parent to super action hero, half-hour fights, 2 to 3 gunshot wounds and explosions put away loose to protect her child from bad boys), it is great to see a story also honored as such differently works - namely "realistic". Though not as nervous tugging like or "Rear Window", "Vertigo", this is all in all a great thriller that leaves the viewer inside the action enough time to follow the events and ask yourself: "What would I in make this situation? ", rather than the default (often flat) history with all the thrilling action, insanity effects and fast pace simply to accept, in the fear that they could lose the connection. Beautiful strip for demanding film fans.
