On Filicudi, a volcanic island in the Aeolian archipelago, a biologist has created, with a few assistants, a first aid center for marine animals, specializing in the sea turtles (Caretta caretta) that once nested in the archipelago. Their presence is frowned upon by the indigenous fishermen who cannot bear to have lost the privilege of the sea and the pleasure of eating turtle meat. In their journeys to save the sea, above and below the surface of the water, these women acquire the experience of ocean and air currents, come into contact with the ancestral beliefs of the island collected by an anthropologist, and become the protagonists of a real and imaginary meta-morphosis at the same time. Rescuing turtles produces extraordinary results that only satellite technologies can capture in their magnificent entirety.
