On October 11, 1999 one day before the anniversary of his father's death, 36-year-old jaded cop, John Sullivan, comes across his father's old ham radio. It is a night of bizarre weather, with the aurora borealis dominating the night sky and, as John plays around with the radio, he finds himself talking to a man who sounds strangely familiar. When he discovers the man is in fact his father talking to him on the same day but in 1969, John realises he has the power to save his father from dying and create the future that might have been. It is a chance no loving son could pass up, but one that ultimately plays with destiny, bringing with it another terror for John's family to endure - one that must be fought on both sides of the time barrier. Dennis Quaid (Any Given Sunday) and Jim Caviezel (The Thin Red Line) star in the exhilarating supernatural thriller about re-writing history, re-creating the future and changing one's destiny forever, Frequency.
