Toni (Ernest Prakasa), Aghi (Ardit Erwandha), Bubu (Tatjana Saphira), and Saras (Beautiful Permatasari) are rich kids who are despised by their friends in a high school, because they always feel pretentious and arrogant. One day they get the assignment to write an essay about the social problems from Mr. Adam (Pandji Pragiwaksono). Instead of writing essays they build a school for poor children under a bridge. At first they think it lightly, but it turns out it is not as easy as they has imagined. A lot of stumbling blocks: the chief scavengers, Toro (Arie Kriting), maughty child, Ucok (Iqbal Sinchan), and Mak Rambe (Gita Bhebhita), his mother who does not agree Ucok to join the school. Not to mention the teasing of their friends at school, headed by Edwin (Rangga Azof) who always underestimate them.
