You are all I have.

Two girls are travelling on a train without tickets and, seeing the controller, decide to escape by stealing money from a local musician. At home, their mum is waiting for them and she surrounds them with love and care. At night they fall asleep to their mother's lullaby, but in the morning they wake up to the harsh reality: the house has long since burned down and their mother is gone. Guardianship comes for them again, and the girls are taken to the orphanage. During the long drive to the orphanage, the car breaks down and the girls decide to run away while the guardian sleeps and the policeman fixes the car. They run into the unknown, hearing the echoes of their mother's lullaby and feeling her support.
