Filmmaker Nancy du Plessis first noticed the Mormon missionaries in the Munich subway. With their white shirts, dark suits and name badges, the shorthaired adolescent boys stood out from the other passengers, nervously talking and joking in American English.

Each year, approximately 60,000 Mormons travel abroad for missionary duty. This religious rite of passage is a crucial one: at age 19, missionaries—who are predominately male—leave their lives behind and, often with their families footing the bill, devote two years to spreading the faith across the United States and throughout the world. GET THE FIRE! Young Mormon Missionaries Abroad follows three boys from their homes in Salt Lake City through their training and service in Germany. What is it like for them to leave their families behind, move to a foreign country and talk to people about God in a language they barely know?

The film opens with Utah teens Jake Erekson, Brady Flamm and Matt Higbee and their families celebrating the boys’ mission assignments to Munich. Two months later, the three young men are undergoing intensive preparation at the Missionary Training Center, where leaders admonish a roomful of teenagers to address each other only as "Elder" and "Sister” and to read aloud from the Missionary Handbook each day—and to follow its rules to the letter.

Once in Munich, Elders Erekson, Flamm and Higbee are sent to live in different cities with their "companions," fellow missionaries of the same sex that they are required to keep within eyesight and hearing 24 hours a day. GET THE FIRE! tracks these pairs through their strict daily routines, which they must plan and document by the hour: proselytizing in a snowstorm, knocking on strangers’ doors in the evening asking to be let in to discuss The Book of Mormon, singing German hymns in big missionary meetings. For the entire mission, they must break completely with their past lives. Phone calls home are allowed only on Christmas and Mother’s Day. No first names, newspapers, movies, television or radio is permitted, in addition to the usual ban on alcohol, coffee, tea and tobacco.

Interspersed throughout footage of these three young men are interviews with five former missionaries who have subsequently left the Church, including Adam Bass, who grew up Mormon and was sent home three weeks into his Chile mission because he was gay and Robert Shiveley, who married a member and became unable to reconcile the Church’s teachings with his own intellect. GET THE FIRE! examines how the missionaries serve out their time abroad and return to Utah as local heroes—despite culture shock, pressure, hard work and isolation—and leaves the audience to ponder what the young Mormon missionary program is about.

“I did not make a film about the Mormon Church. I made a film about young people who went through this experience and came to different conclusions,” says filmmaker Nancy du Plessis. Read more about the filmmaker's perspective in the Filmmaker Q&A.
