Ex-police officer Dexter Parisius, his best friend Rudy Teeuwe, the son of an underworld boss, and the former animation girl Daisy solve various cases that are located on the border between the upper and lower world. Rudy and Dexter want nothing to do with the law, they use their own methods. Rudy talks for fifteen minutes in an hour and prefers to do three trades at the same time. Dex doesn't like to talk much, especially not with the types that bother him. Then a fist or a firearm achieves results much faster. The beautiful Daisy is the only one who can influence these wayward men.
