To Homer Smith (Sidney Poitier), an overheated engine is just an overheated engine; to Mother Maria (Lilia Skala), it’s divine intervention.
Either way, it disrupts Homer’s drive through the Arizona desert at the beginning of the 1963 film Lilies of the Field and prompts him to seek water at the nearest building. This turns out to be a convent, home to Mother Maria and four other nuns (Lisa Mann, Isa Crino, Francesca Jarvis, Pamela Branch) who have come to the United States from East Germany. “God is good. He has sent me a big strong man,” Mother Maria declares upon seeing Homer, then informs him that she has work for him to do. Although he’s not interested at first and starts to drive away, the nuns’ sad faces bother him, and a glance into his wallet reminds him that he could use the money; he is, in fact, an itinerant laborer, and this job is probably no worse than any other he might encounter. As such, he agrees to fix their roof, intending to leave as soon as he’s finished — but Mother Maria has other plans for him.
