Return of the absent (1947)

The boy runs away from his parents' home and his mother dies of grief over him. Time turns against them and their situation worsens, and their hope becomes that the absent son will return. A young man arrives at the house, impersonating the absent son, but as soon as he sees the kind father and the gentle sister, his heart overflows with repentance and love, and he devotes his life to serving them and making them happy. He becomes passionately in love with the girl who thinks he is her brother.
