While out late at the park, capturing ambient sounds for a low-budget slasher movie, a young audio engineer (John Travolta) accidentally records a fatal automobile accident. He’s able to rescue the passenger, a delirious young woman, but the driver is left DOA at the bottom of a lake. We’ll soon learn that the victim was an important political figure and Travolta’s recording contains proof that this was no mere accident. What follows is a hearty dose of suspense mixed with intrigue, as the villains slowly tie off loose ends and various innocent parties stumble into the crosshairs.

Travolta provides a surprisingly adept leading performance, effortlessly cool and on-the-ball alongside a creepy supporting turn from John Lithgow (young but already balding) as the callous hatchet man who successfully spins a serial killing spree into cover for the real story. Nancy Allen (then married to director Brian De Palma) is sufficient as the bimbo survivor / love interest, a walking, talking time capsule who manages some strange natural chemistry with the star. De Palma’s direction takes unusual risks which almost always pay off. The most memorable example is a mesmerizing split-screen act that conveys important plot details via TV news broadcast while also establishing the engineer’s meticulous studio work in parallel. The story feels a little dated, but the daring production concepts are way ahead of their time.
