Soriano brothers Dennis, Chip, and Jeff are bums who do odd jobs to earn a living, including driving a jeepney. Their lives take a different turn after meeting Atty. Aga Agaton, who told them that they are long-lost grandsons of a USA-based millionaire. According to the will, the brothers would get the inheritance when they finish high school. The brothers enroll at Rajah Putih High School where their age turns them into the butt of their classmates' jokes. They eventually befriend a group of students after saving them from bullies. They also seek help from Einstein, the class' resident genius, in order to get away with the most difficult subjects.
