Marty (Timothée Chalamet) may be just a simple shoe salesman, but that doesn't stop him from dreaming of the big time. He fantasizes all day long about becoming world champion in table tennis. Or rather, he's already convinced he's one of the best table tennis players in the world. So, for him, it's only a matter of time before reality catches up. He sees his big chance in a tournament, for which Marty flies from New York City to London. But there, he's confronted with the harsh reality of the sport, which requires a bit more than just self-confidence. In the final, he loses to the Japanese player Koto Endo (Koto Kawaguchi). But Marty isn't ready to give up and starts scraping together the money for the next tournament. This time, he has to win, otherwise, Marty might really be stuck in his uncle's shoe shop for all eternity...
