The Sun is Setting Soon.

A young journalist, who is following an old case, reunites a estranged father and daughter. At that moment, another father appears. And so the fathers begin to compete to make their daughter their own. They don't know whose daughter they are raising. But the unfortunate fathers later realize that the daughter is not their child, but an orphan who has become the servant of a female prisoner. The idea that "a father's love can win anyone's heart" is conveyed in this film.
