Trucking
was a popular movie theme during the early years of overland
shipments with engines that could increasingly go the extra miles. It
was a noisy, physical job to pilot a tractor or single-axle truck
during the 1940s and 1950s. Sabotage was a sure bet premise. This film is not subtle about addressing this
as the opening scenes use a constant barrage of trucks—at
least one miniature—crashing
over a cliff on a mountainous section of “jinxed” Highway 13. Out of sequence is a sedan that enthusiastically powers over a cliff. The driver, Whalen, survives, but his
wife, the heiress to the trucking company, does not. After a period
of recovery, he returns to the office and expresses to the owner his
concern that the rash of driver eliminations is more than accidents.
He seems sincere. He later meets the truck driver who found his wife
after the fiery crash. Lowery. Imagine his surprise to see that Walen
survived.
Bevins, whose age seems to always be pushing ninety, regularly checks the trucks over before the drivers hit the road again. Adjacent to the studio garage set is a diner set where Blake takes short orders. Lowery is a regular customer and after their back-and-forth teasing quips, it is apparent they are planning a future together. As per usual, Bevins is likable as “Pops” with disparaging remarks about coffee's effect on him. Not entirely on the up-and-up, however, he starts spreading rumors that Lowery may be responsible for the rash of crashes.
Walen hires a private detective to pose as their newest driver to investigate the sabotages. Expect the usual sped-up truck sequences as they power around a curve like a sports car. He and Wrixon try to pin his “accidental” death on Lowery. The climax involves an unconscious Lowery, a stowaway Blake and truck pilot, Bevins. With a strong bit of suspended disbelief, you might accept the unlikely and clichéd final sequence.
Note: One interesting historical element is the lost art of using a manual choke lever on the dashboard. Before electronic fuel injection, a manual choke provided a way to get the right mixture of fuel and air in the carburetor. It was mainly used during cold starts, especially in winter. A full choke at start-up, however, might “flood” the engine with too much fuel, making it nearly impossible to start immediately and a short waiting game ensues until the fuel drains from the carburetor. Once underway, pulling the choke all the way out would provide enough fuel to keep a vehicle slowly rolling without a foot on the accelerator pedal. Lowery does this early in the film (albeit a studio prop truck) as he opens the door, places his left foot on the running board and stands to get a better view of an accident ahead. Bevins also uses the manual choke in the movie's climax for his stunt double to jump from a moving truck.
