Death Water (2006)

Newspaper correspondent Kyoko Togakure (Haruka Igawa) visits a nursing home in the outskirts of Tokyo. She finds the dead body of a resident. It was an apparent suicide. He's holding a piece of paper with the mystifying word "Death Water" written on it. Nearby are blood-stained scissors, and his eyes are squashed. She has no idea that this death is just the beginning of a horrendous nightmare.
