Alain Guiraudie

This blend of psychological thriller and hardcore homoeroticism depicts a secluded French beach populated by men who skinny-dip in its lake and then head off to the nearby woods for anonymous hook-ups. But when one witnesses a murder, the setting's idyllic nature is altered - not that this will stop him embarking on an affair with the killer. Winner of Best Director in the Un Certain Regard section of the 2013 Cannes Film Festival.
