Paranormal phenomenon: the curse of the house (Culmination franchise), Odessa

Many years ago, a family with three daughters lived in this house.
The mother practiced secret rituals, trying to "protect" the children from death.
She opened the door to another dimension, not realizing that she was letting in not a protector, but an entity that feeds on children's fear.
The ritual failed.
The house became an anchor.
And the entity - part of its walls.
When the mother realized what she had done, she tried to close the portal...
Using her own youngest daughter as a "key".
Since then, the house has been taking girls to maintain balance between the worlds.
Each new family lived peacefully for exactly 21 days. On the 22nd, power outages began.
On the 23rd, the girl began to complain that someone was calling her name.
On the 24th, she disappeared.
If the ritual is not stopped by midnight, the house will choose a new victim.
And maybe… he has already made his choice.
