In a quiet Southeast Asian town, 'overachiever' cop Yu Dahai (Eddie Peng) has done his job too well, keeping the crime rate at zero for seven years. But no crime means no need for cops, and the station is facing closure. With their careers on the line, Dahai and his squad decide to manufacture a major case to prove their worth. But bad timing is everything. Just as they start faking it, a real gang of tomb raiders arrives. Led by Luo Hao (Zhou You) and Luo Siji (Allen), the thieves are hunting for a legendary treasure buried in an ancient tomb... right under the police station floor.
