The cashier, Jurgen Borb, has already worked for 10 years at Dadag in Hamburg and is an example for customer service and company loyalty.  His loyalty and professionalism are matched by the trust of his employers, who, while relating to him in an acceptable manner professionally, desire no closer contact with him outside of the workplace.  When Borb suddenly disappears one day, Dadag's directors and Borb's colleagues are surprised.  They become even more surprised when they soon discover that Borb has embezzled well over a million Marks from the firm.  His stepsister, Mette, doesn't believe that her stepbrother is an embezzler.  In the meantime, she has fallen in love with a criminal investigator, who, she believes, is simply exploiting her affections to get to Borb.  Then one day, the criminal investigator finds a body in the cellar of a house Borb rented under a false name and this man created a phony ID card for Borb, identifying him as a resident of a South American country.  But are things really as they seem?
