Beth Raymond (Shannyn Sossamon) is terrified by the deaths of four friends, three of which she personally witnessed, after they received chilling phone calls apparently from themselves in the future, showing the exact time of their deaths. After every death, a small red candy is found in the victim's mouth. Beth reports these strange occurrences to the police; however, they think she is delirious. Detective Jack Andrews (Edward Burns), however, believes her, stating that his sister died in a similar way. Together, they begin to unravel the mystery of the chain of calls, but are unsure if they can figure it out before Beth's phone starts to ring the same eerie tune.
