A young Chinese boy assimilated into a Japanese death cult makes a clandestine vow to seek revenge on his ruthless captors, and safeguard his homeland from spiritual destruction. Vajra was just 8-years-old when he was torn from his family in China, and forced to kill for Japan's nefarious Temple of Hades. Years later, Vajra (former Shaolin monk Xing Yu) has earned a reputation as the Emperor's top assassin. But Vajra has never forgiven the temple for causing the death of his brother, and after escaping back to China, he begins a grueling campaign to bring down the Temple of Hades with his bare hands. Now, the very people who shaped Vajra into a lethal weapon will find out just how much damage he can really do.
