The film is set in a South American jungle prison during a revolution. Initially, the camp commander and the prison physician, Dr. Costa, wait for a few guards on a truck. On board are six young women. Three of them were arrested on suspicion of revolutionary activities, the other three are made available to the guards to be raped. The three detainees, Karine, Barbara, and Aida, are found shortly thereafter, naked and chained in a standing position, in the notorious Cellblock 9. Gradually, they are presented to the "interrogation", which is supported by the doctor through various tortures. Barbara and Aida resist the torture and remain silent, Karine, however, breaks down under the torture, and some revolutionaries denounced the (unnamed) city.
In the meantime, the young indigenous student Marie also ends up in the cellblock. Allegedly, propaganda material was found on her by the insurgents. Their torture was to spend three days without food and water in a single cell. She was then taken to dinner with the commander of the doctor, where they have oral sex in order to then get a little sip of salty Champagne.
After the four women in Cellblock 9 again are forging among themselves, they devise a plan to contact their contacts in the capital. The quartet manages to distract the guard in order to knock him out and flee with his rifle. Shortly after leaving the cellblock, Aida is killed in a gunfight with another guard who is also killed. The other three flee into the jungle, where Barbara has been shot and they progress slowly. They make it to an old temple, where they feel safe and remove the bullet from Barbara's shoulder. Karine and Marie go into the jungle to look for food, but the guards find their trail and meet them at the temple. As Barbara is killed, the other two, alerted by her screams, run back to the temple and are suddenly confronted by the camp commander and the doctor (surrounded by prison guards). In a last desperate action Karine attempts to steal the commander's pistol. When she fails to pull the trigger, the commander gives the order to fire and the last two prisoners are struck down on the spot. With the desecration of the corpses, the film ends.
The film was first released in West Germany on 17 March 1978. In addition to its original title, the film is also known as Escape from the Island of Death. In English-speaking countries it is also known as Tropical Inferno and Women in Cellblock 9.
In the United Kingdom, the film was refused classification by the British Board of Film Classification (BBFC) in February 2004, with the board citing potential legal issues under the Video Recordings Act 1984, as well as pending updates made to the Protection of Children Act 1978 in England and Wales (under the Sexual Offences Act 2003) set to take effect in May 2004, as issues prohibiting the classification of the film.
Reception
A retrospective review states that "The story for this one is just like all the other films from the time period. We find pretty, young women who are forced to be nude most of the film and are degraded physically, mentally, and sexually. The story is one tracked and leaves very little for the viewer to grab hold of. The film moves as a snails pace and the dialogue is very tedious."[1] The same review adds that this film is one of the rare films by Franco the author would not recommend.[1]
