Roy and Roger run the local gas station. All sorts of different people come there with their problems concerning cars and other things. A beige customer sneaks around the station all day, without being noticed, a man keeps demanding his white Opel back, since Roy and Roger have lost it and a mysterious blue Volvo 240 turns up every day, without anybody knowing where it comes from. The authorities want to tear down the station and build a freeway instead, but the brothers aren't too keen on the idea, even though Roy is much more opposed to it than Roger. All is mixed with various songs and funny gags.
