After saving the life of one of the civilians inside, firefighter Jack Morrison (Joaquin Phoenix) finds himself trapped in a burning warehouse with a broken leg. As his friend and mentor, Deputy Chief Mike Kennedy (John Travolta), tries to negotiate a rescue from without, Jack flashes back to various events in his life: the first, awkward days on the force, meeting the woman (Jacinda Barrett) who would become his wife and saving a small girl from a burning building.
