After ninety-nine days of severe drought, the peasant Zhao Shoushan uses the last half-ladle of water in his home to revive a mysterious seed, which unexpectedly grows into a gigantic tree shooting straight into the clouds, and a vine throne descends from heaven to take him up to the sky. The spirit deer saved thirty-five years ago appears, and the ancient tree in the clouds reveals the secrets of heaven and earth. The greedy wealthy man Qian Wancai commits evil step by step to seize the divine fruit, almost bringing down a black rain that would destroy the earth. A test concerning the survival of the entire village descends, and Zhao Shoushan makes his choice with his original heart, finally realizing that the true reaching to heaven is never ascending to the sky, but people being willing to share water and build bridges among human hearts.
