"Based on the real life of Dr. Marcel Petiot. During World War II, Petiot, an MD living in occupied Paris, promised to help wealthy Jewish people among his patients to flee occupied France for Spain. Instead, he drugged them and burnt their bodies in his home, while stealing their valuables. After the Liberation of France, he was condemned to death." This was a hard flick to watch and will not be one that many do watch. Couldn't find a trailer for it so if your interested you might have to do some leg work to track it down.
Someone more vile then the Nazis!
