Rachel Keller(Naomi Watts) is a journalist who decides to go undercover on the mysterious death of her niece and her three friends, who seemed to all died on the same day at the same time- 10:00 PM. After being told that her niece was found in a closet with a horrifying look on her face, she searches through her room and finds some pictures, pictures of the cabin where her niece and her friends had stayed a week before the deaths. Rachel finds the cabin and finds an unknown video there. She decides to watch it there, and now has only a limited time to live. She and her divorced husband, Noah(Martin Henderson), research about the video and find facts about Anna Morgan(Shannon Cochran) and her daughter, Samara Morgan(Daveigh Chase), the maker of this video. With only a week left, Rachel and Noah discover the unknown secrets of the life of Samara Morgan, and, hopefully for them, a way to break the curse.
