While recording sound effects for a slasher flick, Jack Terry stumbles upon a real-life horror: a car careening off a bridge and into a river. Jack jumps into the water and fishes out Sally from the car, but the other passenger is already dead — a governor intending to run for president. As Jack does some investigating of his tapes, and starts a perilous romance with Sally, he enters a tangled web of conspiracy that might leave him dead.

With a story inspired by Antonioni's Blow Up and a style informed by the high-gloss suspense of Hitchcock, DePalma's Blow Out is raw, politically informed, and littered with film references.
