The trailer for Gao Qunshu’s Three Old Boys.

The era of the new generation is coming. While the Internet, artificial intelligence, and other high technologies are applied in all aspects of life, crime technology, and criminal investigation are also upgrading day-by-day. In such fast-changing times, the three retiring policemen, Cui Tiejun (by Huang Zhizhong), Xu Guozhu (by Jiang Wu), and Pan Jianghai (by Guo Tao), may not be able to keep up with this new era. The three old boys had to use their “outdated” detection experience against new kinds of crime they’ve never seen, meanwhile, to confront various forces.
