It is believed that American artist Ed Ruscha produced a mysterious object in 1979, a fake rock in the Californian desert that no one seems to be aware of. Almost 40 years later, director Pierre Bismuth sets out to find this hidden piece, with the help of a private detective and two screenwriters.

Join the filmmaker and a hilariously stern private investigator on a most unique case: the search for Pop artist Ed Ruscha’s enigmatic, long sought after fake rock located somewhere in the middle Mojave desert. An endlessly inspired fusion of truth, fiction, and the many possibilities of art.
