One of several British melodramas picked up for American distribution by Columbia in the late 1950s, The Long Haul stars Victor Mature and Diana Dors, two of the prettiest and most amply endowned screen personalities of the era. Mature is cast as American ex-GI Harry Miller, who takes a job as a truck driver to support his British war bride Connie (Gene Anderson). It isn't long, however, before Harry is blackmailed into joining a smuggling operation run by the conniving Casey (Liam Redmond). His resolved momentarily weakened by his obsession with gang moll Lynn (Diana Dors), Harry finally decides to turn honest again--if the other crooks will let him live that long. Director Ken Hughes adapted the screenplay from a novel by Mervyn Mills.
