"Quand il est arrivé à Paris, Koudelka avait déjà réalisé deux reportages de première importance.

Inconnu en 1970, il était déjà l'un des photographes les plus puissants de son temps.

Centre Realms focuses on Will, a young, struggling man facing the possibilities of loss. An eccentric business trip leads him and a co-worker to the North pole, an expedition to potentially help in the fight against pollution. A bizarre misfortune leads Will to confront the possibilities of debunking one of the Earth's strangest conspiracy theories - Middle Earth. It is the belief that other forms of life may be living in wide open spaces and caverns hundreds of miles beneath our feet. After Will's boss agrees to cover the expenses needed to accomplish such a feat, experts are employed and the possibilities of success start seeming likely. However, as investigations occur, one problem leads to next, including mental and physical trauma throughout the trip. The team wonders whether the descent into the earth is worth the danger, as events begin to spiral out of control. Meanwhile, Will worries about the amount of time available for one last goodbye to the one he loves most.
