An American doctor (James Stewart), his wife, a former singer (Doris Day) and son decide to spend some time in Marakesh where they meet a couple in the hotel. Whilst visiting the market they witness a man being murdered and then the other couple kidnap their son. They then travel to London to try and find their son and stop a diplomat being murdered. This is a typically well produced Hitchcock thriller with good performances from both James Stewart and Doris Day. This Hitchcock's remake of his own 1934 version.
