La Mécanique du Rasoir (2006)

Aloïs de Snefeler, a maniacal executioner, dotes on his companion. She goes by the sweet name of Louise and does her father, Dr. Ignace Guillotin, proud. At the widow's feet, heads roll. But not just any heads... The executioner's favorite prey is female. Thieves or adulteresses, magpies or impious women, peasant women or courtesans, they all end up with their heads in the basket. Around Aloïs, the ranks are thinning, but beware! ... He who cuts last cuts well!
