The Brown family, which consists of Hon. John Brown, his wife, two sons, Harold and Billy, and a young sister named Helen, has settled on an isolated plantation in the Jungles. Jack Arden, son of another English planter, who comes over frequently to hunt with the boys has fallen in love with Helen. But Papa Brown discourages the lovers, saying that Helen is too young to be married. Jack agrees to wait. Some time afterward the Browns receive a letter from Jack stating that he is coming for another week-end of shooting- with the Brown boys. On his way to the Brown's home, Jack knocks down Concho, an overseer, for being cruel to one of the slaves. His action is approved of by the Browns. In honor of Jack the family starts on a lion hunt, and, after a long trip, they return by the river route. They espy a lioness drinking at the river's edge. She is killed by Jack and taken aboard. That night Jack again asks Mr. Brown for Helen's hand and is again told to wait. The next day when Jack is going away, Helen, unknown to anyone else, accompanies him a little way into the jungle. Concho sees this and follows, until he sees them part. On the way home Helen dismounts and starts to pick some wild flowers until her attention is attracted by a lion cub. She ties her horse to a tree and trails the cub. She is followed and accosted by Concho. At the moment when she seems to be at the complete mercy of this half-breed brute, a leopard leaps from the undergrowth and attacks the villainous overseer. While the half-breed fights desperately with the ferocious beast. Helen makes her escape. She manages to make her way back to the spot where she left her horse, but, discovers a huge lion devouring the mangled remains of her mount. Terror-stricken she runs aimlessly into the jungle where she is soon followed by the lion and its mate. Concho, in the meantime, has managed to escape from the leopard. He crawls back to the plantation and accounts for his wounds by maliciously declaring that Jack Arden had abducted Helen and made off with her. Brown and boys start off in pursuit of the alleged kidnapper. The posse overtakes Jack only to discover they have been tricked by the malicious half-breed. The mystery of Helen's disappearance is still unsolved and Jack, beside himself with lover's grief, returns with the party to organize a searching expedition. In the meantime Helen has been chased to the banks of a river by the frenzied lions. In her fright she falls from a cliff into the stream below. She swims through the turbulent waters to the opposite bank and once more rushes into the dense brush. The maddened lions follow her through the water toward the opposite shore. The searching party is coming down the river at this time on rafts. Jack Arden's raft rounds a bend in the stream just in time for him to see the lions plunge into a thicket. Simultaneously he hears a scream and realizes that it emanates from Helen who lies at the mercy of the beasts. His rifle springs to his shoulder and two shots ring forth. The shots are guided straight to their mark by the unerring aim of true love and Helen is saved just before her life is crushed out by one of the wild beasts. When Jack reaches her side the huge lion is actually found dead and is lying over her body. Helen has sustained but slight wounds, and the clasp of Arden brings her back to life.
