« Want to save the Amazon rainforest ? Fuck ! » That's the catchword of the « Fuck for forest » collective. These activists, eccentric and very queer, put videos online of them and other volunteer's being filmed naked or having sex. The benefits go to the environment ! From Berlin (a shared community) to the depth of Amazonia (meeting natives threatened by rainforest logging), we follow the day to day of a sexually and ecologically surprising revolution.
