Su Wan worked in a funeral home for three years but never told anyone her real secret - she could hear the last heartbeat of the deceased.
That voice was not last words or resentment, but a melody, which was different for everyone. Some are broken strings of pipa, some are broken glasses, and some are just long sighs like a flat tire. Su Wan secretly recorded these sounds, anonymously made audio files and uploaded them to the Internet, with titles only containing dates and numbers.
Her account was called "Seven Days Countdown", but no one paid attention to it at first. Until one day, a young detective named Lu Chi accidentally heard recording No. 047 While handling a case - it was the last heartbeat of his partner who had been missing for three years.
Lu Chi followed the account information and thought he had found the murderer's accomplice, but he met Su Wan head-on in the cold storage room of the funeral home. He held the handcuffs and she held the recorder, with a body in between that had not yet been cremated. Su Wan didn't run, she just handed him the recorder and said, "Listen again, that's not the sound of fear, it's him saying goodbye to you."
