Frequency

Frequency (2000) is an American sci-fi thriller directed by Gregory Hoblit — watch it online on iFILM. New York cop John Sullivan, played by James Caviezel, switches on his late father's ham radio during a rare aurora and hears a familiar voice. It belongs to Frank, played by Dennis Quaid — a firefighter who died in a blaze thirty years ago.

John warns Frank in time, and Frank survives. But changing the past reshapes the present in ways neither man expected: a serial killer's victims shift, and a cold case reopens across two timelines. The film turns a single prop — a battered shortwave radio — into a device for both a murder mystery and a father-son story. Stream Frequency (2000) online on iFILM.
