While at the station, Bong-gu leaves his lighter in a bathroom stall, where it is purloined by a gangster, Yang Chul-gon (Cha Seung-won). Enraged beyond endurance, Bong-gu demands the lighter back, provoking a beating from the gangster's underlings. Undeterred, he follows Chul-gon onto a train. There, Chul-gon has more important business to attend to, waylaying a senator (Park Yeong-gyu) whom he had helped into office but who has since refused to reciprocate with any political favors. When the senator stubbornly refuses to concede, Chul-gon takes the entire train hostage. Meanwhile, Bong-gu will stop at nothing to recover his lighter.
