Penumpasan Sisa-sisa PKI Blitar Selatan (Operasi Trisula)

(title translation: Destroying the Remains of PKI in South Blitar (Trisula Operations), PKI is the abbreviation of Partai Komunis Indonesia or Indonesian Communist Party)

Members of the G-30-S PKI (Indonesian Communist Party) movement flee from Jakarta and other regions when they are discovered. They survive and organise movements in the areas south of Blitar, which are barren and hilly, littered with hidden caves. They are depicted as people who commit robberies, sabotage, and a public nuisance. A military operation, Trisula, is formed to eradicate them. With no shades of subtlety, the film comes across as propaganda than for its original intention as docudrama.
