Julia, a woman suffering from a degenerative sight disease, finds her twin sister Sara, who has already gone blind as a result of the same disease, hanged in the basement of her house. In spite of the fact that everything points to suicide, Julia decides to investigate what she intuitively feels is a murder case, entering a dark world that seems to hide a mysterious presence. As Julia begins to uncover the terrifying truth about her sister's death, her sight deteriorates, until a series of unexplained deaths and disappearances cross her path.
