Mak Irit is famous for her special ability to make something bigger, and also smaller, hence her nickname Mak Irit (Ms. Economical). In her school where she teaches this ability, the "MAK IRIT COLLEGE", she has three well-known students: Miss Resita, Papi Ray, and Sukino. Then Mak Irit comes to Jakarta to pass on a special skill to one of them. The problems start when she arrives in Jakarta. Sukino is a relaxed bajaj (small public transportation) boss. One day he falls in love with Nanny, who is the daughter of his enemy, Papi Ray. But Nanny is already arranged by her parents to marry Brandon.
