Two tiger cub brothers are town from the jungle and taken to Rome. The stronger cub is trained as a killer at the Coliseum. Emperor Caesar makes a gift of the smaller cub to his beautiful daughter, Aurelia. She adores her cub, Boots, and Julius, a young animal keeper, teaches her how to earn the tiger’s trust. Boots is pampered while his brother, known as Brute, lives in a cold and dark cage, let out only to kill. Caesar trusts Julius to watch Aurelia and her prized pet. But when a prank backfires, Boots temporarily escapes and Julius must pay with his life. Thousands watch as Julius is sent unarmed into the arena to face the killer Brute.
