Island of Despair (1969)

spanishcastlemoviemagic.com

A group of inappropriately dressed women are rowed ashore to the prison camp known as the Castle of Death, built by the Spanish we are told.

And it’s not surprising as we are in fact in Alicante.

The first few minutes show us the castle from various viewpoints before the mistreatment and slapping begin.

As director Jess Franco indulges his taste in soft porn with a minimum of plot, we see views of the castle periodically, both within and without, until three girls escape and plunge into the Brazilian jungle.

After a ration of sex and violence they are recaptured, and in the last scene we see them lined up, back again in the castle.

Herbert Lom’s presence as the sadistic warden doesn’t improve matters much.
