| Item | Details | |------|---------| | | 19 April 2011 (first reports) – incident fully confirmed 27 April 2011 | | Platform | KRI Cakra‑402 (type‑209/1300 diesel‑electric attack submarine) – colloquially nick‑named “Caged” by its crew because of a faulty hatch‑seal that “caged” the boat underwater. | | Location | Off Banda Sea , western Indonesia, ~45 nm southeast of Sumbawa Island . | | Mission | Routine anti‑submarine warfare (ASW) training exercise with the surface fleet of the Eastern Fleet Command. | | Outcome | The sub lost propulsion and surfaced in an uncontrolled manner, forcing the crew to remain sealed inside for 48 hours while a rescue operation was staged. All 38 crew members survived, but the incident exposed critical gaps in the Indonesian Navy’s (TNI‑AL) submarine safety and crisis‑response procedures. | | After‑action | Full‑fleet overhaul of hull‑integrity inspection regimes, installation of a “Cage‑Recovery System” (CRS) on all Type‑209s, and a joint Indo‑Australian submarine rescue exercise (MALABAR 2012). |
Days pass. He runs out of water. He hallucinates. He sees his mother’s ghost. He writes frantic notes on the wall. This is where Caged 2011 Sub Indo becomes essential. The subtitles capture his broken Spanish, shifting to delusional whispers. Caged 2011 Sub Indo
| Effect | Technical Detail | |--------|-------------------| | | Diesel‑electric drive stalled; batteries drained as auxiliary pumps fought the ingress. | | Loss of Communications | The main VLF antenna was mounted near the forward hatch; once water shorted the circuitry, the sub could not transmit on the standard 3 kHz channel. | | Forced “Caged” Condition | The crew sealed the forward compartment, sealing themselves inside the pressure hull for 48 hours while waiting for external rescue. The term “caged” was coined by the crew’s radio operator in the after‑action report. | | Atmosphere Depletion | CO₂ scrubbers operated at 70 % capacity; oxygen levels dropped to 18 % before emergency oxygen bottles were used. | | Item | Details | |------|---------| | |
Without spoiling the ending, the film answers the question: Who built this cage? And why? The answer is not a serial killer, but something far more terrifying and existential. | | Outcome | The sub lost propulsion
