The Heart Sutra

The painter Yuan Zaifang feels restless day and night for running out of inspiration for creating better works. He plans to go to the feast of his freind for fathering a baby upon his invitation through phone. His friend Qin Daming asks him to deliver a cloth bag to a long-time no see friend Qiansui by the way. Failing to know Qiansui’s whereabouts, he goes to meet Qin Daming by the side of a temple as agreed.
They come to the mountain behind the temple. In front of the stone grave full of autumn grass, Qin Daming confesses a secret hidden in his heart for ten years. What is the connection between the stone grave, the cloth bag and Lao Gan, the owner of the yard of stones Yuan Zaifang has passed by? In the reality and dream of burning desire, how does Yuan Zaifang renounce evil and turn to virtue like the others?
