For those who don't know the Grudge(or is not a fan like me), here's basically what it's about.
There is a curse, born of a powerful rage. It gathers in the places where the dead once lived. And if you cross its path, you die by its fury. But now, one survivor will learn the truth about a brutal murder, a missing child, and the chain that can't be broken.
This movie is a really good thriller.
