It's either from the 80s or 70s and its about some kids that runaway, (may be have a goal) may be two teen-aged kids and two or tree more little. I have a vague memory of it. But have a rare scene fist: A chubby girl that have their first period. The teen-aged girl helped in a pier, but leaves in a police department. When the mother picks up in the police department, slaps him. Thanks in advanced.
