Neptune's Closet.

From the director: "I set out to look at a case of police surveillance and infiltration, to listen carefully to the songs and signs of a secret society, and in the end, I turned towards the study of a life. I uncovered a book that was kept at the club in 1914, and in it, a poem about the author’s special friends: sea snails. When faced with ostracizing opprobrium and hate, it is moving to remember so many of us turned in solitude toward Nature, and to the Sea."
