Spring 2019, the world watched in stunned silence as Notre-Dame de Paris burned, leaving it in ruins: its spire and roof gone, part of its vaults collapsed. 18 months later, a massive restoration is about to begin.

But how to rebuild a gothic cathedral without knowing how it was constructed? How to give it back its soul, acoustics and light, which are the very essence of a sacred monument?

These are the great challenges of the restoration, to which science will contribute with the opening of a major archaeological site within Notre-Dame itself. Over 200 experts have united to study the stone, timber and metal remains in order to uncover the secrets of it structure. They’ll use a new tool specially designed for this colossal task: a 3D digital model of unequaled power. With unequaled access, this documentary follows this amazing scientific adventure as Notre-Dame is brought back to life.
