Su Heng is a psychic. Her world is stitched together by silk threads, and her soul is like a puppet, quietly walking in the theater of forgetfulness. Her mission is to talk to those souls that no one remembers, cut the threads of bondage for them, and let them complete their unfinished escape. But tonight, Su Heng met a soul who refused to be liberated - he longed to forget and did not want to be awakened. On the stage, the dialogue between Su Heng and him was like needle and thread intertwined. On one side was the desire to escape from memory, and on the other was the obsession to save the soul. She began to wonder whether rescuing others was compassion or another kind of prison. In this game between the puppet and the puppet master, Su Heng must choose: to be the one who cuts the thread, or to be the shadow pulled by the thread. Forgetting may be the last freedom of the soul.
