Lin Zhou stumbles upon a director system with peculiar rules and welcomes a seven-day filmmaking challenge. He invites the sincere and vibrant Su Wan and the calm and meticulous Zhou Ye, along with partners, to step into the Changhe Cinema, using his lens to record forty-two years of screening time here. The old projector turns once again, performances in the rain happen naturally, neighborhood residents bring their treasured ticket stubs into the lens, and one life story after another converges into a movie. After the work goes live, viewers actively share it, Su Wan gains more attention, Zhou Ye welcomes new performance opportunities, and the Changhe Cinema lights up once again. From this filming experience, Lin Zhou understands the meaning of creation, cherishes the trust of his partners, and also finds his own direction.
