Set against the backdrop of the Japanese occupation and traditional Betawi culture, the story centers on Sayuti, a brash local champion consumed by jealousy over his dancer girlfriend, Nonon. His insecurity deepens with the arrival of Komar, an educated urbanite who quickly gains the villagers' admiration. Unbeknownst to Sayuti, Komar and his comrade Malik are actually resistance fighters operating undercover within the Japanese ranks to steal weapons. When Sayuti impulsively decides to prove his worth by attacking the occupiers directly, his reckless heroism threatens to blow the cover of Komar's carefully planned operation.
