Lan Sheng: a name that has left countless legends on NBA courts. In his rookie season, he led the Golden State Warriors to the top. Over the next four years, he won four more championships, cementing his place as a basketball legend with the terrifying dominance of five titles in five years.
Just as fans around the world anticipated an even greater dynasty, the 24-year-old suddenly announced his retirement, stunning the entire sports world. What no one knew was that Lan Sheng had awakened the “Lie-Flat System.” The more completely he took it easy, the stronger he became, so the youngest five-time champion in history promptly chose to go home and enjoy retirement. He thought he could spend his days fishing and drinking tea in peace, but the filming of the domestic hit reality show Five Hahas (Hahaha Haha) completely upended his quiet life. His cousin Lu Han and his close friends Chen He and Deng Chao sweet-talked and tricked the homebody superstar into joining them on their misadventure for the sake of the show. Faced with three troublemaking friends who are naturally hilarious, Lan Sheng, who only wanted to keep a low profile and lie flat, is forced to get back to work. From hardcore hikes in the Xinjiang desert to hilarious misadventures in the snowy villages of the Northeast, the cameras capture three older buddies and their genius younger cousin causing chaos, while behind the scenes Lan Sheng grumbles but goes along with it. When an elite athlete’s physical prowess meets Five Hahas’ absurd challenges, a road-trip comedy about youth, friendship, and the ultimate contrast between appearances and reality begins.
