In Tengchong City, Yunnan Province, China，an ancient art from the Central Plains is passed down - shadow play. Two hundred years ago, the shadow play tradition came here, took root in this land, and developed its own outstanding characteristics. This film focuses on the scenes of Tengchong shadow play, not only showing how the old artists protect the traditional skills with their vicissitudes of life, but also keenly capturing the innovative attempts of the younger generation of inheritors. Light travels through shadows to become a play, which continues to thrive in the south of the colorful clouds… A lamp, a curtain, and a variety of human life.
