Pingkan (Velove Vexia), a young lecturer in Japanese Literature at the University of Indonesia, has the opportunity to study in Japan for two years. Sarwono (Adipati Dolken) is sad to learn that she will be leaving him behind. Sarwono is commissioned by his chief to present a cooperation to Sam Ratulangi University, Manado. Sarwono brings Pingkan as his guide while in Manado and she meets his father's extended family. She begins to be cornered by questions about her relationship with Sarwono: in their eyes the difference is huge. Not that Pingkan and Sarwono do not realize it. They are already comfortable staying for years in a soundproof room called love.
