What really happened on the 'Sex Raft'
The true story behind an infamous social experiment
In 1973 Mexican anthropologist Santiago Genovés decided to create an experiment to find out what drives people to commit acts of violence. He put a group of men and women from different parts of the world on a raft and cast them out to sea. What happened was not what he expected though, as we hear from three of the women who took part - Fay Seymour, Edna Reves and Maria Bjornstam. (Photo credit: Modern Films.)
