The human brain performs astonishing feats. Neuroscientists attempt to understand how the brain works and find themselves confronted with the most fundamental questions about humanity: how is our personality connected to the structure of our brain? Could computers develop consciousness? Can the "I" be found in the brain? Do human beings have free will? Is consciousness? possible without a brain? Are the experiences of God or transcendence merely an illusion of the neuron? This documentary takes you on an interdisciplinary journey with neuroscientists, philosophers, theologians, all asking these great questions, and points to where science exceeds its limit to become a worldview.
