Korean remake of a Japanese movie, the Ring.
After the mysterious death of her niece and other three teenagers on the same hour and with the symptoms of heart attack, the journalist Sun-ju decides to investigate their last moments. She discloses that the four friends had just watched a videotape exactly one week before their death in a resort. She travels to the place and finds the deadly video and after watching the weird footage, her telephone rings. When she takes a picture of herself, she sees her image blurred the same way that happened with the teenagers. She makes a copy of the cursed tape to her acquaintance, the skeptical coroner Choi Yeol. Together they seek for a hint, and find that it was taped thorough telekinesis by Eun-suh, a psychic girl that had disappeared years ago. When Sun-ju's little daughter watches the movie, Sun-ju has a stronger reason to unravel the mystery to save her daughter and her own lives.
