The seven-story tower stands there like a concrete tomb rising from the asphalt. In this film, which seems to have leapt from the dusty pages of action and drama, Lin Bing focuses on a life spiraling out of control over a matter of money. The character Bruce Li finds himself caught in the middle of a dark scheme he unwittingly became entangled in. The fact that his girlfriend is being held hostage in the same tower takes things to an entirely new level. In this vertical hell filled with martial arts masters, a different trial awaits on every floor. The one-way climb gradually intensifies the silence and tension within.
