The righteous ranger Xin Lan (Xiao Xun) feels powerless in her dull job and wants to leave. But Ade (Su Da), who used to be a wood-stealing mountain rat, pesters Xin Lan and persuades him to go up the mountain with his hunter friend Dumas (Sakinu) to retrieve the precious cypress that they had hidden secretly before. The three of them accidentally met the artist Patrick (He Linjun) on the mountain. In order to stop him from committing suicide, they had to drag him up the mountain. They finally climbed to the place where the cypress was hidden. Xin Lan was determined to stop Ade from illegally stealing wood, and the mountain rat who followed them secretly also showed up to steal the cypress. Everyone was deadlocked on the mountain. How will this journey end smoothly?
