Cheol-woong, a newcomer, is assigned to Rescue Unit of the Fire Station in Seoul. Soon he is sent to his first mission with Jin-seop, a veteran fireman working with a glorious title; the man who saved the highest number of people in the fire. While being overwhelmed by fierce fire and pouring smoke, Cheol-woong witnesses that Jin-seop forces to search the occupant contrary to the chief’s withdrawal order. Just before the fire gobbles up the building, Jin-seop manages to escape with a girl in his arms, but a colleague loses the life. Cheol-woong's fear becomes an anger against Jin-seop, and blames him for his colleague’s death. When their conflict is still at the peak, they’re called for another fire scene which changes their fate for good.
