After graduating from high school, Lupus was not accepted at a public university and forbade his mother to sell inherited jewelery so that Lupus could enter a private school and cover his debts. Lupus asks for a down payment from the magazine where he often writes with the promise of writing about teenage girls who like to come home early. He then interviewed and approached Pia {Paramitha Rusady} who went to the disco every night because the house was crowded. His widowed father only scolded him but was rarely at home. Disco is a place of entertainment. She's not like other disco girls, who are also sex-free etc. Writing about Pia had invited misunderstandings, so Lupus preached. And it is said that his father then wanted to change his attitude. Pia's story is intertwined with: catching frogs, applying for jobs that turn out to be unsuccessful.
