Country music and a good mood - the summery trucker festival in Frontenhausen, Lower Bavaria, provides asphalt cowboys with just the right change from the tough everyday life of truck drivers. Here the men finally have time to celebrate. Only transport company Marten has to work on the freeway. This time he has reinforcements on board, because his father is helping him out. But the first problems arise when the trailers are coupled up. Meanwhile, colleague Andreas enjoys the relaxed atmosphere at the festival and is also finding inspiration there in terms of truck refinement. And yet, his truck is already award-winning, just like the one of his colleague Sigi. Driver Piet, on the other hand, doesn't think much of thick engines and expensive equipment. He turns back the clock and trots through the Emsland region with horse and cart, just like the carters in the past.
