The Ring (2002)

It sounded like just another urban legend: a videotape filled with nightmarish images, leading to a phone call foretelling the viewer's death in exactly 7 days. Newspaper reporter Rachel Keller (Naomi Watts) was naturally skeptical of the story -- until four teens died mysteriously one week after watching such a tape. Curious, Rachel tracks down the video and watches it … and now, she has just 7 days to unravel the mystery of the "Ring."
