在方济各担任教皇的头九年里，他进行了37次旅行，访问了53个国家，聚焦在他看来最为重要的问题：贫困、移民、环境、团结和战争。罗西被教皇方济各的两次旅行事迹所深深吸引，第一次是探望在兰佩杜萨登陆的难民；第二次是2021年对中东的访问。像是电影《海上火焰》和《夜曲》中呈现的，罗西也跟随着教皇的十字架，在旅程中亲身经历了方济各的所见所闻，融合了方济各旅行的档案片段以及自己所拍摄的影像，在过去历史和当今世界状况之间用纪录片的形式创造了一种对话。

The ground shakes periodically and the fumaroles of the Phlegraean Fields taint the air. From the traces of history, memories of the subterranean world, and the concerns of the present, in black and white, a lesser-known Naples emerges and fills with voices, with lives. Below the clouds lies a territory crisscrossed by locals, worshippers, tourists, and archaeologists excavating a past that in museums will give new life and meaning to statues, fragments, and ruins. The train that rings Vesuvius makes its rounds as racehorses train along the shore. A teacher runs a makeshift afterschool for children and adolescents. Firemen in their command center calm the fears of the locals who call in, law enforcement tracks down tomb robbers, while in the port of Torre Annunziata, Syrian tankers unload Ukrainian grain. The land that skirts the gulf is a vast time machine.
