The devil Lou is supposed to turn the Engel family into devils. This is the one job below his level and far too much in his opinion. The four angels live related in a roast idyll. The father, Rainer Engel, is a health insurance employee, but an application cannot be made. The mother, Karin Engel, is a tax specialist in rights. The two children, Stella and Marc Engel, cannot harm a fly either.
