My First Client (2019)

Based on a real crime that happened in 2013: a 10-year-old girl confesses that she killed her little brother by beating him up. An unsuccessful lawyer who started working at a regional children's center, met these siblings before it happened, but he wanted success as a lawyer and cared none for children's welfare. He left the area after he got hired at a big law firm, but he decided to give up his future, and came back to sincerely help the girl in her misery.
