The entire company heads to a hundred-story KTV for a team-building event. Lin Feng foresees the boss's impending mutation but is mocked and doubted by sales supervisor Zhao Kuo. Overwhelmed by the negative energy of workplace exploitation, the boss mutates into a gigantic monster made of time clocks, shredders, and office equipment, turning the entire building into a deadly trap. Lin Feng joins forces with his close friend Dajun and the boss's wife, Chen Bing, to survive. Selfish and vain, Zhao Kuo repeatedly brings disaster upon himself and even offers his girlfriend, Bai Weiwei, to the monster to save his own skin. Along the way, the security chief dies after underestimating the threat, while the survivors face one peril after another, including mutated giant rats and out-of-control robots. Finally, the trio discovers the ledger documenting the boss's exploitation of employees and plans to use it as a breakthrough to destroy the personification of capitalist monstrosity.
