On a stormy night, an unwelcome guest breaks into the home of Lin Xiaoxing, a 17-year-old high school sophomore: Lu Tingxiao, a warlord from the Fengtian clique in the Republic of China era. This old-fashioned relic, resurrected with unfinished business, is haughty and old-school, calls himself “this marshal,” and knows nothing about modern life, yet he's fiercely loyal and always stands up for his own. To keep his secret hidden, Lin Xiaoxing is forced to launch the “Modernize the Old Warlord” project, teaching him to use a toilet, play with a phone, and adapt to modern rules. Their chaotic life under one roof gradually draws them closer, even as they bicker and get on each other's nerves.
