Beauty contest winner Patricia Knight's one bid for screen stardom was Columbia's Shockproof. Knight plays Jenny Wright, a convicted murderess paroled in the care of probation officer Griff Marat (Cornel Wilde). What begins as an aloof professional relationship eventually blossoms into romance. The fly in the ointment is shady Harry Wesson (John Baragrey), the gambler who inveigled Jenny into committing murder. The girl is torn between creature comforts offered her by Wesson and the promise of a clean life offered by Griff. This early Douglas Sirk effort contains a smattering of the stylistic touches which distinguished his later work.The screenplay was written by famed director Samuel Fuller, known for his gritty realism and hard-boiled style. ~ Hal Erickson, All Movie Guide
