In the summer of 1973, five men and six women embarked on a 101-day scientific sea adventure, drifting across the Atlantic on a raft christened the Acali. Likely one of the strangest social experiments of all time, this voyage, organized by radical anthropologist Santiago Genovés, aimed to explore the origins of violence and the dynamics of sexual attraction, with the handpicked crew of guinea pigs mixing religion, gender and nationality to maximize potential friction on board. This fascinating documentary uses archival footage and a recreated set, assembling the surviving participants to discuss this controversial, 45-year-old experiment that was hyperbolically lambasted by the media as “The Sex Raft.” Writer/Director: Marcus Lindeen.
