Teo-neol

A man, Lee Jung-soo (Ha Jung-woo), is driving through the Hado Tunnel when it collapses, trapping him underneath the rubble. With limited communication, Jung-soo must conserve energy and ration resources to survive, aided by the advice of rescue team head Dae-kyung (Oh Dal-su). As the days pass, Jung-soo encounters other trapped motorists, including Mi-Na (Nam Ji-hyun), and must confront the psychological toll of his confinement, while the rescue operation is complicated by miscommunication, public skepticism, and ultimately, a tragic accident.
