Stip And PensilToni, Aghi, Bubu, and Saras come from wealthy families who are hostile to their students because of their arrogance. One day, they got an assignment to write an essay on social issues from Mr. Adam. Instead of writing essay, they built a school for poor children under a bridge. At first they thought it was easy, but it was not as easy as they imagined. There are so many obstacles faced by the Head of Scavengers, Toro, a naughty child, Ucok, and Mak Rambe, Ucok's mother who does not agree with her child going to school. Not to mention the ridicule of friends at the school chaired by Edwin who always underestimated them.
