Teacher Prapto (Rd Sukarno) helped build the nation by educating the people on a mountain slope in Central Java. One day the mountain erupted, the people fled. Lasmijah (Risa Umami) left her daughter Yati to follow her husband, Prapto. In fact, Prapto rushed home. Prapto only met Yati, and then lived in his hometown, Salatiga. There he met Sutinah (Tina Melinda), then married her. Meanwhile, Lasmijah, who was disabled, looked for Prapto and Yati.
