An ordinary British couple vacationing in Switzerland suddenly find themselves embroiled in a case of international intrigue when their daughter is kidnapped by spies plotting a political assassination. This fleet and gripping early thriller from the Master of Suspense, Alfred Hitchcock, was the first film the director made after signing to the Gaumont-British Picture Corporation.

"In this heart-pounding suspense story, spies kidnap a young girl, in an attempt to prevent her parents from revealing what they know about an assassination plot. The action takes you from the Swiss Alps to Britain's Albert Hall and London's East End."
