As this cinematic adventure unfolds, we find ourselves introduced to Xu Lang, a brilliant scientist portrayed by Xu Zheng. He has unlocked the secret to a groundbreaking invention known as "Supergas," a solution that can significantly increase the volume of any liquid. This remarkable discovery could lead to unprecedented profits, particularly in the realm of valuable resources like gasoline. However, to secure additional funding from a powerful investment fund, Xu must gain the approval of Mr. Zhou, the largest shareholder. Meanwhile, his business partner and former college classmate, Gao Bo, played by Huang Bo, is eager to sell the innovative product to a French corporation instead.
Xu’s determination leads him on a journey to Thailand to secure Mr. Zhou's endorsement in person, but he soon finds himself pursued by his rival, Gao. On the flight, Xu encounters Wang Bao, a lively entrepreneur depicted by Wang Baoqiang, who is on a mission to check off items from his bucket list—one of which includes taking on a Muay Thai master and nurturing a cactus garden. Proudly running a scallion pancake shop in Beijing, Wang claims to be the long-time partner of the famous actress Fan Bingbing, a statement that Xu initially dismisses and regards with skepticism.
As they navigate the vibrant streets of Thailand, Xu and Wang become an unlikely duo in their quest to find Mr. Zhou. Their cultural exchanges fuel much of the film's dialogue as the meticulous businessman and the delightfully naive chef embark on a series of misadventures. However, as frustrations mount over their lack of progress in locating Mr. Zhou, Xu secretly rummages through Wang's wallet and finds a suspicious stash of cash.
Believing that Wang could be spying for Gao, Xu takes it upon himself to read Wang's diary in hopes of uncovering damaging information. Instead, he is touched by the chef's heartfelt entries, which reveal Wang’s efforts to uplift his mother, who battles Alzheimer's disease. Wang's secret crush on Fan Bingbing and his dreams of finding true love also shine through his writing. Moved by these revelations, Xu starts to see Wang as a potential ally once again, and they both press on in pursuit of Mr. Zhou.
The story takes a surprising turn when Wang arrives at a revered temple and is presented with a case housing the coveted authorization letter. The twist? Wang himself must interpret the contents. At the same time, Gao appears with a skilled Muay Thai master, Saichia Wongwirot, in tow, desperate to claim the letter for himself. What follows is a chaotic combat sequence showcasing martial arts prowess, wherein Wang must confront the Muay Thai master as well.
In a moment of inspiration, rather than relying solely on brute strength, Wang showcases an unexpected skill—an acrobatic kick that knocks his opponent to the ground. This encounter becomes the setting for deeper revelations.
Upon examining the letter, Gao learns that its authenticity hinges on his own signature. Concurrently, Xu undergoes a profound transformation, shedding his cutthroat businessman facade and reconnecting with the simpler pleasures of life. His enlightenment is sparked by a rekindling of appreciation for his wife, played by Tao Hong, and their daughter, whose needs he has long overlooked.
As Wang’s Thai adventure continues, he inadvertently checks off every desire he has ever dreamed of. The trip acts as a pivotal turning point for Xu, while Gao manages to receive joyful news about the impending birth of his child over the phone, providing him temporary solace.
In a heartwarming climax, Xu rekindles his family’s bonds, steering them away from the verge of separation, while Wang meets Fan Bingbing, thanks to Xu’s careful arrangements. The actress is touched by Wang's tender love for his mother and happily agrees to pose with him in a photo shoot. As Gao remains in Thailand, mired in passport issues, he finds comfort in the happiness of his loved ones back home.
The narrative concludes on an inspirational note, emphasizing the transformative power of travel, self-discovery, and the enduring ties of family.
