Rosco (Terence Hill) is a globetrotter who hitchhikes through Florida - on roller skates. Doug (Bud Spencer) was released from prison early, not because of good guidance, but because space was needed. They meet in a restaurant and fight against a gang of truck drivers. In a stolen truck, they continue their journey together. Finally, they smuggle themselves into the First Class cabin of an airplane. But the seats were reserved for someone else.. Before take-off, a man hands them a briefcase full of money! Rosco and Doug know that there's a big adventure waiting for them...
