Les nuits de Paris

Georges and Bert are assigned to find an heiress, their only lead is that she's a dancer with the initials MS tattooed on her thigh. The hunt leads them to the bright lights of the music hall where Bert falls in love with an employee, Nicole. She entertains reservations about his moral fiber because of his dutiful attendance at every show where the girls flash the flesh. But when Bert's face is gashed, she agrees to donate some of her skin for a graft. As Bert's bandages are unwrapped, they see the elusive initials etched on his forehead.
