The Case of the Monja Blanca

In the course of a "marriage" swindle, four vicious con-men use a clever ploy by hiring the detectives to prove the integrity and financial security of their next victim. They say that they want to be certain of the quality of the prospective bride's lineage. When the investigation is revealed, the victims feel reassured about the integrity and financial security of the perpetrators. The victim is then cruelly tricked and blackmailed and it is up to the detectives to expose the scheme and prevent further harm from coming to its most innocent victim.
