How do you inform a narrative when the ultimate chapter is public data?
You begin on the finish.
Fireplace of Love, Sara Dosa's shifting documentary about husband-and-wife volcanologists Maurice and Katia Krafft, begins on June 2, 1991, at Mount Unzen in Japan.
The Kraffts, rockstar scientists of their discipline, are seen in a buoyant temper in archival footage.
However narrator Miranda July rapidly punctures that.
"Tomorrow might be their final day," we're advised by way of her voice over.
Unzen would erupt on June 3, killing the Kraffts together with 41 others in a pyroclastic move.
It is an ending so definitive, there was no alternative however to begin there.
"We actually did not need the viewers to be centered on how Katia and Maurice would possibly die... as a substitute, we hoped folks would give attention to how they dwell," the director advised Sara Sidner in an interview for CNN's Amanpour.
"It is a collage movie that is advised by way of... their footage, their pictures, their writings, and we needed the viewers to know before everything that what they're watching is (what the Kraffts) left behind once they handed. So, we needed to acknowledge their demise."
The movie includes excerpts from round 200 hours of footage taken by the couple for their very own analysis and documentaries, together with media interviews and extracts from their books.
Fireplace of Love has drawn close to common reward in evaluations, first at Sundance in January and main as much as the movie's launch within the US and the UK this summer season.
Armed with a 16mm video digicam, the French scientists captured the intimate lives of volcanoes from the Democratic Republic of Congo to Colombia to america.
In vivid hues, lava burbles and races, rocks fly, these agitated mounds filled with sound and fury, wrestling with their inventive and harmful potential.
Working with editors Erin Casper and Jocelyne Chaput, Dosa harnesses the volcano footage's anthropomorphic qualities for instance the Krafft's relationship with one another and their topics.
"We like to think about the movie as a love triangle between Maurice, Katia and volcanoes," she defined.
Katia and Maurice met within the Nineteen Sixties by way of their frequent curiosity.
Their personalities contrasted, Maurice gregarious and devil-may-care, Katia quieter and observant; variations that carried over into their fieldwork.
In a single scene we see Katia unamused as her husband rows out right into a lake of sulphuric acid (after which faces over three hours of paddling right into a headwind to get again to shore).
"It should kill me in the future," Maurice says of his job.
Katia was typically attempting to make sure it did not - even when she was hardly risk-averse herself.
In one of many documentary's many eyebrow-raising scenes, she stands, calm and picked up, on the sting of a crater whereas measuring a temperature of 1200 levels Celsius.
Requested to explain their relationship by an interviewer, Maurice quips, "It is volcanic - we erupt typically!"
"That they had a battle there," Dosa mentioned.
"They had been normally in a position to reconcile although, as a result of they knew that it was so vital to be in sync with one another, to help one another, in the event that they had been going to pursue their final love, which was being near erupting volcanoes."

The Kraffts knew find out how to leverage their daring pursuits to realize fame and financing to proceed their analysis; their image-making was not a selfless train.
Nevertheless it's to Dosa's profit and ours that the Kraffts had been, of their phrases, so "fascinated, like a magnet, getting nearer and nearer" to hazard.
"It is actually because of their love and their boldness, to get so near seize these pictures, that we have now them now in our movie," Dosa mentioned.
And although "they died actually doing what they cherished," their legacy has prevented many extra deaths.
The Krafft's footage of a pyroclastic move in 1986, for instance, was utilized in an academic video to assist governments perceive their risks, the director defined, and every week after the couple's demise its classes had been put into observe when Mount Pinatubo erupted within the Philippines.
"The video helped to avoid wasting many lives," Dosa mentioned.
"It is fairly tragic, however poetic."
