Korea’s most intimidating actor, Heo Sung-tae (Squid Game), stars as Detective Oh Nam-hyuk—a well-meaning but spectacularly inept cop clinging to his badge by a thread. When a botched sting operation lands him in over his head, he’s forced into an unlikely partnership with Tae-bong (Jo Bok-rae), a razor-sharp informant whose cover (and savings) are blown by Nam-hyuk’s bumbling. With a smuggling ring to bust, a fortune to recover, and zero trust between them, the mismatched duo must navigate double-crosses, blown covers, spectacularly stupid raids, and bruised egos.
