Mr Wagiman and his children, Inem and Tarjin, belong to a respected village family. Conflicts arise when Inem is arranged to marry the son of Dono’s family, but the arrangement falls through. So Inem finally goes to Jakarta, with Susy, her best friend. They live with Pakle Bagio and friends, Wisnu and Rendra. Not long after, Tarjin and his friend, Bejah, from the village are invited to Jakarta by Kang Cut, who works for a rich widow, Tetty Qadi Pinky, whose motto is that the customer’s satisfaction is the first priority.

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.
