The big day has finally arrived: Asphalt cowboy Mike Cohnen marries his Bianca! To celebrate the day, the newlyweds are holding a trucker party with a convoy of trucks. Country bard Gunter Gabriel, "the German Johnny Cash", is also in the party and serenades the bridal couple himself. Meanwhile, freight forwarder Dieter Lynen and his drivers unload 20,000 liters of beer on Majorca, and lumber driver Thorsten Eckert is not spared from breakdowns on the forest tour in the Taunus region.
