ความลับในกระบะท้าย

Elaine Crosby and Douglas Miller are a truck-driving couple who live and work on the road. Whenever Elaine drives, Douglas heads to the rear compartment alone, often complaining of back pain. He takes two meals to the back and refuses to let Elaine near. Though suspicious, she keeps quiet for their livelihood. One day, a strange woman’s voice comes from the compartment. Elaine secretly looks and makes a shocking discovery—her husband has been hiding another woman inside the truck.
