Plot

Marguerite and Bob rescue Bertha from Gungha, who has held the girl prisoner. Bertha informs her benefactors that it is because she knows the whereabouts of an old painting which tells where a fortune in gems is concealed, that Gungha had kidnapped her. Later, the Hindu succeeds in again kidnapping Bertha. Marguerite, attempting to go to her assistance, is also entrapped. The two are taken to the house formerly occupied by Bertha and in which the gems are supposed to be concealed. Bob tries to enter Gungha's den, but is overpowered and bound. In spite of the cords which hold him helpless, the boy succeeds in giving the alarm. While the police are coming to Bob's assistance, Gungha, aided by Alota, an accomplice, tries to compel Bertha to reveal the hiding place of the painting by torturing her. Marguerite tries to go to the victim's rescue, but is herself threatened with torture. The arrival of the police, who are accompanied by Bob, results in the capture of the Hindu and his accomplice. After the two are dragged away, Bertha brings the painting to light. A close examination of the canvas gives Marguerite an idea. Taking an old blunderbuss from the wall, she orders Bob to stand in the center of the room, aim towards a certain spot over the fireplace and shoot. Bob follows out Marguerite's instructions. A flash follows the pulling of the trigger and it is found that a key, suspended by a fine wire, hangs from the muzzle and over a tiny hole in the floor. When the key is inserted in this hole, a secret trap opens up and the treasure is discovered.—Moving Picture World synopsis
