Xu Lang, who has sacrificed the past four years of his life to developing a new energy technology, has only a few days to secure power of attorney from his boss so as to close a deal with a venture capital company. He flies to Bangkok, while his wife prepares their divorce papers, only to be followed by his company rival Gao Bo who plans to sell the unfinished technology outright to the French. En route, Xu meets happy-g0-lucky Wang Bao who is traveling to Thailand as a tourist. After losing his passport, Xu partners with the penniless Wang on an episodic journey to Chiang Mai... with Gao Bo in hot pursuit.
