An American romantic comedy tells the story of an author who wrote an epoch-making book about spiritual guidance. Many people are chasing him for some life advice, but he just wants to be alone for a while. As the saying goes, "doctors don't treat themselves." In the movie Dream of the Spiritual Mentor, this sentence was fulfilled on the spiritual mentor Allen. Allen is a reclusive best-selling author. When a bookseller found his address, Allen's troubles followed. Later, Allen fell in love with a single mother and met a frustrated young man. In the process of dealing with them, Allen slowly discovered that there are still many unsolved problems in life.
