Wu Hai, once an architectural genius, was framed, hid in an old alley doing antique restoration, and closed off his heart for three years. Junior schoolmate Su Wan came looking for him to save the old cotton mill auditorium facing demolition, bringing his lost graduation design and evidence to clear his name. Accompanied by Su Wan and awakened by Uncle Lin, Wu Hai walked out of the shadows, joined hands to renovate the auditorium, and cleared past grievances, not only giving the old building a new lease on life but also regaining his original aspiration, harvesting love and a new beginning.
