The Killer (2023)

A man solitary and cold, methodical and unencumbered by scruples or regrets, the killer waits in the shadows, watching for his next target. And yet the longer he waits, the more he thinks he's losing his mind, if not his cool. A brutal, bloody and stylish noir story of a professional assassin lost in a world without a moral compass, this is a case study of a man alone, armed to the teeth and slowly losing his mind.
