Welcome to Hell!

Just as children are haunted by devils, so devils haunt people. Because just as hell is the punishment for humans, the greatest punishment for devils is to go among humans. After all, they are so evil and greedy, they make fun of each other and sew shacks for themselves.
That's why when the parents of two restless devils Albert and Norbert don't know how to direct their sons, they send them among the people. To make them realize that parents are to be obeyed, but also to make up for the one enormous mischief they have committed - to return to hell all the sinners they have set free. Albert and Norbert will have to show a lot of wit and courage and accept that their task will be constantly interfered with by the two capacities that have the most experience in caring for human souls: God and Lucifer.
