From the cage to the big screen, the world's greatest Mixed Martial Arts Champions come together for the first time in a major motion picture. When an MMA world champion is lured into the illegal world of underground cage fighting by an elusive promoter, he quickly realizes that the only way out is to kill or to be killed. In a place where some fight for glory and some fight for the fight; he will fight for his life. Now, in his greatest effort to come out on top, he can never look back; never show weakness, never leave...and NEVER SURRENDER. 配乐比剧情好，女主角的身材比男演员的动作肌肉好看。不以情节取胜。 从拳台到荧幕，世界上最著名的拳击冠军们走到了一起共同出演第一部电影。一位冠军被一位神秘的资助人骗去参加了一个非法的地下拳击组织，他很快意识到唯一出去的出路就是杀人或被人杀。在这里，有些战斗是为了荣耀，有些战斗是为了战斗，而他的战斗是为了逃离这里，他不能回头，不能示弱，不能离开，绝不投降。。。 燕迹秦清添加。
