Flesher (2019)

Two serial killers work together to skin their victims and sell them to an underground flesh market. The skins are preserved, displayed, and auctioned as works of art with values based on the victim's status, wealth, or beauty. When a meeting goes bad and a buyer is killed, pressure from the organization forces the usually-methodical Flesher to take reckless actions that lead to a paranoia he can't escape.
