Five Steps to Danger is a 1957 American film written and directed by Henry S. Kesler and starring Ruth Roman and Sterling Hayden. John Emmett (Hayden) is on a road trip from Los Angeles to Texas when his car breaks down and he is forced to find a ride. When Ann Nicholson (Roman) comes across him, she offers him a ride. As the two venture down the road together, John learns of Ann's life on the lam. She is running from both the police and her physician, for they want to question her regarding a murdered CIA operative in Los Angeles. Ann is in possession of a small hand mirror with the secret formula for building a 4000 miler per hour rocket on the back of it. She aims to deliver it to a scientist here in the United States before she goes back to her home in Berlin, Germany.
