Rohaya (Roekiah) must separate from her lover, Kasim (Rd Mochtar), so that she can marry her father's choice, the disreputable but rich Musa (Eddie T. Effendi). The night before the wedding, Kasim plays the song "Terang Boelan" for Rohaya, and they agree to elope. The following day, Rohaya and Kasim escape from Sawoba Island to Malacca, where Kasim begins work at a drydock and Rohaya keeps busy as a housewife. They discover that Kasim's old friend, Dullah (Kartolo), has lived in Malacca for some time.
