Frequency is a 2000 American science fiction thriller drama film starring Dennis Quaid, Jim Caviezel, Andre Braugher, Elizabeth Mitchell, Shawn Doyle, Melissa Errico and Noah Emmerich.


In 1969 New York, a gasoline tanker overturns on a highway ramp, spilling fuel into an electrical substation below ground and trapping two workers. Among the responding firefighters is veteran Frank Sullivan, who goes underground to rescue the workers against the direction of his commander, and despite the rising level of fuel and the sparking created by damaged electrics. Frank and another firefighter pull the workers out and escape just before a spark ignites a huge explosion, and Frank returns safely home to his wife Julia and young son Johnny.
