He interviews families and observes their daily routines to understand the impacts. By living with one family and interacting naturally, he sees how a child acts on and off their medication. Louis also speaks to doctors and gets their views that the drugs can help children without harming them. The documentary explores different perspectives on medicating children for mental health issues.
