Xie Feng is delivering takeout when he stumbles upon a gang deal, and his younger sister is kidnapped as a hostage.
To save her, he ventures alone into the den of wolves, only to have his legs broken and be thrown into a shipping container to die.
At death’s door, a mysterious stranger appears: “Do you want to live, or die?”
Inside the container, Xie Feng transforms from a deliveryman into the king of underground fighting.
He thinks his path to revenge has finally begun, but then he finds his sister’s bloodstained hair clip backstage at a fight.
“Your sister isn’t dead, but she’s worse off than if she were.” His opponent sneers. “Want to save her? Then win this fight to the death!”
