A homeless girl, Ha-dam, stays in empty houses to get by. In the winter, she leaves Seoul and heads to Busan, searching for work. But it's tough to do much without a phone or address. On top of it all, she is often deceived by adults. On the way to her shelter after failing another job interview, suddenly the sound of tap dancing catches her ears. The instant fascination with the rhythm of tap touches her heart like a magic. From that moment, she starts to dance on the street and to love every moment of it. But the cold reality of life keeps coming toward her like roaring currents.
