Frequency (2000) hinges on a spectral radio frequency that bridges three decades, allowing New York cop John Sullivan to converse with his father, a firefighter who died tragically in the past. This temporal dialogue unravels a web of coincidences and consequences, as Sullivan's attempts to avert his father's death inadvertently set off a chain of lethal events. The film's tight script explores the moral quandaries and emotional stakes of manipulating history, grounding its fantastical premise in palpable grief and familial longing.
