In a century-old house in the water towns of Jiangnan, the four Yang sisters are dragged into a land inheritance battle over property worth 300 million yuan after their father’s funeral.
The eldest, Ruolan, is gentle and reserved. She inherits the largest share and becomes everyone’s target. The second, Ruzhu, is shrewd and forceful, and doesn’t hesitate to take her own sister to court over the family fortune. The third, Ru Mei, seems frail on the surface, but secretly conspires with the developers. The youngest, Ruju, is innocent and cheerful, the only one in this bitter struggle still trying to hold on to their family ties.
Strange things keep happening in the old house: sobbing in the dead of night, unexplained bloodstains, bones in the attic, and a terrifying presence at the bottom of the well. Someone disappears. Someone is pushed into the well. Someone is frightened into a mental breakdown in the middle of the night.
As the truth is gradually revealed, the four sisters discover that something is more terrifying than the 300 million yuan in compensation: a secret buried for twenty years. Their mother did not die of an illness. Someone pushed her down the stairs and killed her. The murderer is one of them.
The sisters turn against each other, mother and daughter tear each other apart, and betrayal hides among those closest to them. When every mask is torn away, all that remains in the old house is shattered family ties and three hundred million yuan in bloodstained bills.
In the end, the money is divided and everyone goes their separate ways. But the old house remains, and the sisters will return, carrying their scars and the words: “Sis, it’s daylight.”
