Swain and Conklin, two international secret service men of questionable reputation, have taken up headquarters in an underground refuge from which they direct their operations. They are engaged in an effort to steal a valuable code book from Prime Minister Cogley. The butler in Cogley's home is also in league with Swain and Conklin and he keeps headquarters in constant touch with developments. Swain forges a letter which Conklin presents to the Prime Minister who believes him to be a representative from a friendly country. In the home of the Prime Minister, Conklin becomes smitten with the Prime Minister's daughter and immediately forgets his mission, devoting his time to paying attention to the girl. The butler notifies Swain and he forces Conklin to leave her and return to the den while the butler, who has stolen the code book, gives it to Swain and is sent to plant an infernal machine aboard a yacht which brings the girl's sweetheart, Harry, to port. Harry goes to Cogley to ask him for the girl's hand and is ejected from the room by the cranky father. Conklin, in trying to make good with Swain, sneaks back into the house and steals what he believes to be the code book and triumphantly brings it to Swain who, upon examining it, finds the Prime Minister's diary. Swain, who has received the real code book from the butler, wrecks his vengeance on Conklin and tells him that the girl on the yacht will be blown up at a certain hour. Conklin proceeds to get into communication with the boat by wireless in order to warn them of his discovery, but is discovered by Swain and bound and gagged. Swain then gets into a racing automobile and makes a dash to the lighthouse to darken the light and let the yacht run on the rocks. A traffic officer pursues them and many thrilling incidents occur before the lighthouse is reached. Conklin is discovered and freed by the secretary, and immediately charters an aeroplane and hastens to the lighthouse. Cogley returns to his his desk, misses the code book and seeing Harry's hat on the table infers that he is the one who took it. Cogley warns the police of the theft and all start toward the boat. Conklin lets a rope down from the aeroplane and drops into the lighthouse where Swain has extinguished the light. Swain discovers him and a chase ensues which winds up with Conklin grabbing a rope on the aeroplane, but as he leaves the top of the lighthouse Swain also catches on the rope, and the two battle in midair. Conklin finally knocks Swain off the rope and he drops into the boat which has been deserted by all on board when the bomb is discovered. The boat is blown up while Swain is on board. Conklin, seeing the girl marooned on the rocks, orders the aeroplane to the rescue. Conklin drops from the rope into the water and rescues the girl, bringing her up to shore where he finds her father and her sweetheart, Harry. Expected to be rewarded for saving her life, he asks Cogley for her hand. The girl refuses to have him and returns to her sweetheart while Conklin weeps out his troubles on the shoulder of the forgiving Prime Minister.
