Synopsis 3
How would you like to have a lunatic surgeon perform various operations on you? Pleasant prospect, that! Well, here's a yarn about a chap wrecked on an island, the sole inhabitant thereof being a "batty" surgeon with a mania for exploring the interior arrangements of every human being he met. How the shipwrecked mariner escapes from the deadly attentions, or intentions, of the locoed doctor makes a thrilling tale, unusual and novel in the extreme and "The Island of Terror" will long be remembered as a masterly George Kleine adventure story. It is in two reels and every inch is full of action.

Plot
Dr. Wagner is conducting scientific experiments into pathological problems. However, his colleagues are extremely skeptical about these experiments, and voice sharp criticism. Anguish and bitterness consume the young researcher's senses and one day, he and his wife, disappear...

Some months pass. Following a tremendous storm, the sea casts up an exhausted human form onto the shore of one of the small islands which dot the Pacific Ocean. A familiar figure, in the company of several natives, comes to the unconscious man's aid, and has him carried inland to a hut. The castaway is George Ramsay, an American journalist, and his rescuer none other than the half-crazed Dr. Wagner, who has withdrawn to the island in order to continue his studies and experiments into the composition of human blood undisturbed. Ramsay soon becomes aware of the doctor's mental state, and since he finds himself being held on the island practically as a prisoner, he determines to flee in secret. He finds a comrade in Wagner's young wife Betsy, who had joined her husband against her will, and whose greatest desire is now to escape from this environment of fear and horror. The artful Ramsay succeeds in constructing a raft without being detected, but on the very evening that the pair had elected to flee, the doctor and his assistants storm the hut in which Ramsay had been staying, in order to seize him and employ him as a 'guinea pig' in the doctor's experiments. The attacked man defends himself desperately and, with a superhuman show of strength, is able to break free. He takes refuge in one of the many caves located in the island's cliffs, but the doctor deploys bloodhounds to track down the hiding place, before filling it with smoke to force Ramsay out into the open. Thankfully, the journalist discovers a second exit to the underground grotto and finally reaches the beach, where a panic-stricken Betsy is awaiting him. The raft constructed by Ramsay carries the pair out to the high sea. At dawn, a trading ship spots and rescues them, while the raving mad Dr. Wagner, following a terrible fight with his assistants, sets his house alight and perishes in the flames...
