I live in an old dormitory building that has been rotten for twenty years.
Every household hides dark secrets.
Ma Tao is a scoundrel who is hated by everyone in the building. He relies on taking advantage of everyone, extorting money and running rampant.
Until late one night, he mysteriously fell from the seventh floor to his death.
The neighbors in the entire building unanimously chose to remain silent and tacitly agreed to cover up the truth.
I accidentally discovered the black notebook left by the deceased, which recorded the sins and scandals of each family.
And the last page contains my forbidden secret that has been kept in dust for twelve years.
There is a murderous intention hidden in the corridor, and the neighbors have their own agenda. The murderer who committed the crime late at night was hiding next to me.
I gradually understood that there were never innocent people in this old and dilapidated residential building.
The whole building is an accomplice!
Motto: Silence does not mean innocence
