The tale deals with a marriage (Leslie Banks and Edna Best) and their daughter (Nova Pilbeam) on holiday in Saint Moritz , Switzerland . They are witnesses for the assassination of their friend Louis (Pierre Fresnay) , before giving them a message and then they become involved into a confuse and obscure international plot , concerning their abducting daughter .
The movie gets the seed in which later emerged many Hitchcock's suspense pictures . In fact , Alfred Hitchcock reverted back to the more familiar territory of a suspense/intrigue thriller after the lousy result in Walzes from Vienna (1934) . It has a typical theme of the suspense master : innocent people become caught up into a cobweb of intrigue . The film displays interesting issues and a good cast , as an excellent Peter Lorre in his first English role , he interprets a clever and uncanny villain . However , the plot isn't narrated in agility and it seems some forced . The film highlights are the following ones : the happenings at the Royal Albert Hall of London , the rescue of the kidnapped daughter in the Tabernacle of the Sun and the final showdown remembers the authentic events on riots in Sidney Street , year 1911 , where a lot of citizens died . At the time the general public loved it and obtained smash-hit . Hitchcock's remade in 1956 is considered much better and with more lavish setting and glimmer color , besides , being starred by James Stewart and Doris Day singing : Que sera , sera . Rated : Good but dated .
