A man, Tolbiac, wakes up on a dark environment and tries to figure out what happened and how he was founded there. This place used to be an underground research lab, known as Eden Log. An experiment about new methods of collecting energy from the trees. Scientists and workers started a small revolution and guards had to take them down as they started transforming into mutants. Even the creator of the Rezo labyrinth can't help our hero as he is now a part of the deep roots of the toxic plants. Tolbiac will meet a young botanist and together they will try to escape from this land of desperation. Will they make it? An interesting dystopian film with social futuristic comments, dark atmosphere and cinematography and a working script even if its action was sometime recurrent and maybe slow.
