Marty Supreme follows 1950s New York shoe salesman and hustler Marty Mauser (Timothée Chalamet) as he aggressively pursues his dream to become a world champion table tennis (ping-pong) player, leading him into increasingly chaotic schemes, from hustling for cash and a wild affair with a washed-up Hollywood star (Gwyneth Paltrow) to getting involved with gangsters and trying to fund his journey to international tournaments in London and Tokyo, all while his life unravels with a pregnant girlfriend and mounting legal troubles, blending sports drama with a frantic, character-driven odyssey inspired by real-life player Marty Reisman.
