A shipwreck survivor, Edward Parker, is picked up by a freighter and brought to a mysterious, uncharted island. The island is controlled by the enigmatic Dr. Moreau, a scientist who has been exiled from civilization due to his controversial experiments. Moreau invites Parker to stay on the island, where he quickly learns that the scientist has been conducting horrific genetic experiments, attempting to transform animals into human-like creatures. These hybrid beings, known as the "beast-men," follow a strict set of laws imposed by Moreau, who rules over them with an iron fist.

Suspicious and increasingly horrified by Moreau's cruel methods, Parker seeks to understand the full extent of the atrocities occurring on the island. He befriends Lota, a woman with a mysterious past who becomes a key figure in his quest for the truth. As Parker delves deeper into the island's secrets, he faces escalating danger from both Moreau and his creations. The claustrophobic atmosphere and mounting tension drive Parker towards a desperate struggle for survival, forcing him to confront the nightmarish reality Moreau has built.
