Echo in Silence

Strange things happen frequently in Building 7, Hongqi Lane, which is about to be demolished. The sound of marbles late at night, the warning note "Don't go to the top floor", and the missing residents with amnesia make Lin Mo, the social worker in the building, suspicious. Lin Mo conducted an in-depth investigation with the obsession to find out the source of her grandmother's fear, and accidentally got involved in the unsolved case of a little girl who fell to her death from the top floor twenty years ago. A lonely maintenance worker, a mysterious tenant, a retired criminal police officer, and people with their own secrets are intertwined into a network. When the truth was revealed on a rainy night, the guilt and redemption that had been buried for twenty years finally came to an end amidst the sound of demolition.
