The summer holidays have just begun in Brandenburg, but 10-year-old Lea does not go to camp this year with her friends. She stays alone in the village, visiting Mark, an old musician. One afternoon, Lea discovers five boys lifting a large blue oil barrel on a bicycle trailer. Lea’s curiosity is aroused, and she follows them. From this point, the summer seems to be full of adventures. The movie was selected at Film Festival Max-Ophüls-Preis.
