This mystery melodrama was based on a novel by British author William Garrett. Antonio Moreno stands out as Guy Fenton, an American newspaper correspondent based in London. When he rescues a girl in distress he embroils himself in a mystery. The girl, Marion (Lillian Hall), has an uncle who has been murdered by fortune hunters. The code Fenton discovers leads him to a country home where his every move is watched. The house itself is full of hidden panels and secret passageways. In spite of these obstacles, Fenton is able to find the hidden book containing the rest of the code, which reveals a treasure that is buried in the Scottish highlands. He also discovers a trap door which leads him to a secret chamber where a band of counterfeiters have been doing their dirty work. Fenton manages to fend off the bad guys and recover the treasure, along with winning Marion.
