After the end of the Second World War, the fighting continued in some parts of the world, as colonized countries struggled for independence. In the setting for this film, Indonesian soldiers have already won freedom for the island of Java, but on Kalimantan, called Borneo by the colonizers, Dutch soldiers remain. One day they bombard a village and only the Indonesian Captain Bitah survives. Under dramatic circumstances, he manages to reach Java on a raft. There, he establishes a small partisan unit dropped from an airplane over the Kalimantan jungle. During the descent, one of the paratroopers is severely injured and another one, the telegraphist Sarto, loses the transmitter in the moorland. Dutch soldiers find the parachute and begin to pursue the partisans.
