Deep water freediving exposes its practitioners to a form of narcosis, which induces several symptoms, among which a feeling of euphoria and levity that earned this phenomenon its nickname of "raptures of the deep". The short film relates the interior journey of Guillaume Néry, the apnea world champion, during one of his deep water dives. It draws its inspiration from his physical experience and the narrative of his hallucinations.

Free diver Guillaume Néry swims to the depths of the oceans, and allows us to explore a world that is usually out of reach.
