Tang Sen, the manager of the "Xitian Group", a gold-medal collection team, uses ruthless methods to scare the old man. There are four "King Kong" under his command: the violent detective Sun Xiaosheng, the slippery intelligence agent Zhu Bajie, the silent thug Sha Wu, and the cold-hearted analyst Bai Ling, each with their unique skills in collecting debts. However, fate suddenly changed! Tang Sen's investment was in trouble, and the five masters and apprentices were involved in huge debts one after another, and they were reduced from "hunters" to "prey". The methods used in the past—exploding address books, door-to-door threats, and even Sun Xiaosheng's "golden cudgel" POS machine and Tang Sen's "tightening curse" mobile phone bombing—are now backfired on themselves. In the embarrassment of avoiding debt and the torment of conscience, they witnessed the suffering of all living beings: communities being squeezed dry, mothers in despair, and hypocritical "saviors." Forced to join forces and struggle to survive, they used their "professionalism" to fight back against their sinister creditors, but offended the behemoth "Tianting Technology". When a bigger financial shady situation approaches, can this group of "fallen kings" recover their conscience buried by money on the thorny road of paying off their debts and fighting injustice? The road to redemption is also the road to crusade!
