Metamorphosis is a real ballet dance on the rocks, interpreted by a great climber, Patrick Berhault, and set in the picturesque countryside of Cote d'Azur and the Lingurian coast. Berhault's evolutions, in the sea, in the grottoes, on the rocks and precipices, are exceedingly difficult but they are chiefly performed to give the movement an aesthetic value. Matemorphosis is the story of a cycle without words, narrated with gestures and music. The climber Monique Dalmasso also partecipates in the film.
