法國大革命期間，路易十六和皇后瑪麗·安東妮被控與外國勢力密謀推翻大革命。君主制度被廢除，路易十六被判死刑，1793 年1 月21日被斬頭。瑪麗安東妮也受了審判並在幾個月後被處決。鮮為人知的是，他們被囚禁在聖殿塔中幾個月，等待死亡。影片重溯了這段等待的日子和王室沒落戲劇性的情節。

In the past few days Rome has been the scene of a singular event: when it rains, the manholes exhale a dense steam whose origin and composition is unknown. No one can imagine that whoever breathes in the mysterious substance will have to deal with what he/she represses, their darkest instincts, their anger. Not even the Morel family.
