Mario is sitting in a bench thinking about the disease his family is suffering (you can hear his thoughts)
In his way school he finds some friends, he talks with them about his situation and they advise him to search for more information about the disease, and to look for a way to solve it or at least make it better.
Mario starts investigating about the disease, ways to get over it, prevent it and help his family. Then he founds about the SDG 3 and looks for help for his family.
In his home, he talked with his sister about an investigation in a hospital near their house, where they are treating people with the same disease as his family and that is for free. Also that many people was having a succesful result.
Mario called the hospital and asked for information for his family situation and also asked why the investigation started. They explained him that it is a project based on the United Nation SDG 3.
Mario talked with his mother about the investigation and about what her sister and he were planning. And she is surprised and asks him about the investigation and how is that going to work. While they are talking Mario narrates what happened after that.
