in Feng (Liu Haoran) thought he was going to attend his distant uncle Tang Ren's (Wang Baoqiang) wedding, which turned out to be a hoax. Tang Ren had deceived Qin Feng to come to New York for another purpose. The godfather of Chinatown, Uncle Qi (Kenneth Tsang), gathered the world's best detectives from an app called Crimaster (which allows real detectives to upload their cases for the online community to solve them) and sets up a competition to locate his grandson's killer within one week for a reward of five million dollars. His grandson Jason was found in a temple with his heart torn out and an unknown symbol on a table near him.
