A romantic triangle complicates a big-game hunting expedition.

Big game trapper Harry Stanton is commissioned by a West German zoo to go to the Malay jungle and capture a rare breed of cat called "The Enchantress," a combination of tiger and leopard. Accompanying him is Otto Abbot, a professional hunter, and Otto's mistress Anna. After netting two tigers, they set out after their prize quarry. Friction develops between the two men when Harry makes it apparent that he intends to take Anna away from Otto, although Anna rejects the trapper's advances. They trap the sought-after animal in a cave, and Otto tries to prove himself by entering the cave armed only with a blazing torch. He is badly mauled; but Harry comes to the rescue and captures the huge cat. Once back in Germany, Anna admits to Otto that she has fallen in love with Harry. While they are taking the Enchantress to its destination by freight train, the jealous Otto releases the animal when Harry is alone with it in the baggage car; but his life is saved when the van doors are opened, and the cat leaps from the train. After killing a janitor, the cat stalks the roof of an apartment house. Harry and Anna, both armed, follow it, only to discover that Otto is already on the trail. He attempts to shoot Harry but instead is killed by the snarling cat, which is then shot by Anna.
