The Fugitive (1963)

While working as a truck driver for a small freight company, Kimble discovers that his angry and bitter boss, Gus Hendrick, is being blackmailed by Lucia Mayfield, the wife of his late business partner, into paying her bills and for child support since Mr. Mayfield was killed a year earlier in a driving accident. But Kimble later learns that with Hendrick strapped for money, and Lucia merely squandering the blackmail money for her own selfish purposes, Hendrick plans to hijack one of his own trucks to collect an insurance settlement.
