Plot

Daffy decides to hitchhike south but struggles to catch a ride. He tricks Porky into giving him a lift by painting a fake hole in the road. Along the way, they encounter a menacing driver, leading Daffy to comically grovel to avoid confrontation. Daffy's reckless driving gets them into trouble with the law, resulting in a fine. Despite Porky's warnings, Daffy's antics lead to another hefty fine. Fed up, Porky seeks revenge by tricking Daffy into launching himself with his own luggage. Later, Porky gifts Daffy a hitchhiker's thumb, which Daffy naively uses in vain. The cartoon ends with Daffy nursing his bruised thumb, a victim of his own folly.
