Plot Summary (Blow Out) Blow Out
Jack Terry records a sound he wasn't supposed to hear
Jack Terry (John Travolta (in Blow Out, as actor)) is a sound-effects technician working on cheap slasher films in Philadelphia.b2 One night he's out recording ambient sounds — wind, crickets, an owl — when a car blows a tire on a bridge, crashes through the guardrail, and plunges into a creek.b4 Jack dives in and pulls out a young woman, Sally Badina (Nancy Allen (in Blow Out, as actor)).b5 The driver — a man named McRyan — is dead.b6
The dead man turns out to be the next president
McRyan is Governor George McRyan, the front-runner heading into the upcoming presidential primaries.b3 The official story is a tire blowout — an accident.b29 But when Jack plays back his recording, he hears something before the blowout: the sound of a gunshot.b9 The tire didn't blow — it was shot out.b15 The accident was an assassination.
Jack assembles the evidence and no one cares
Jack synchronizes his audio recording with still photographs taken by Manny Karp (Dennis Franz (in Blow Out, as actor)), a sleazy photographer who was coincidentally shooting the bridge that night.b11 By combining the photos with his soundtrack, Jack creates a crude film — a Zapruder-film reconstruction — that proves the assassination.b12 b21 He takes his evidence to a detective, who dismisses him as a conspiracy nut — a special commission is already forming to declare the death an accident.b17 A television reporter named Frank Donahue offers to put Jack on the air,b20 but Burke has tapped Jack's phone and is already working to destroy the evidence.b19 b30
Sally was part of a setup that went wrong
Sally, it turns out, was placed in the car as part of an unrelated scheme. Karp had been hired to photograph McRyan in a compromising position with a young woman — a classic political dirty trick. Sally was the bait.b21 b22 The assassination happened independently, turning Karp's blackmail setup into a murder scene.b24 Sally is caught between the conspiracy and the cover-up, and she's a liability to both.
Burke kills to keep the secret buried
Burke (John Lithgow (in Blow Out, as actor)) is the assassin — a contract killer posing as a political operative.b18 To cover his tracks, he begins murdering young women in Philadelphia, staging the deaths as the work of a serial killer.b29 His target is Sally, but by killing other women first, he creates a pattern that will make her death look like just another victim of a random predator.b18
Jack tries to save Sally and fails
Jack wires Sally with a microphone for a meeting with Donahue during Philadelphia's Liberty Day celebration — not as bait, but because he suspects his phone has been tapped and wants to monitor the exchange.b30 b31 The man who shows up is not Donahue but Burke, impersonating the reporter.b32 Burke steers Sally onto a train, out of Jack's monitoring range, takes the film, and lobs the canister out the window.b33 Jack hears Sally calling his name through the wire and races through the city, but crashes his Jeep.b33 He arrives too late. He holds her body as fireworks explode overhead — a grotesque, beautiful image that mocks the very idea of American celebration.b34 b35
The ending weaponizes Jack's skill against him
Back in his studio, Jack plays Sally's death scream — the recording from the wire she was wearing — into the slasher film's mix.b38 Sam is delighted with the sound.b38 Jack says it three times to himself: "It's a good scream."b39 Each repetition lands emptier than the last, a man trying to convince himself that what he has done is professional rather than monstrous.
