The trailer for Lisa Russell’s newest film opens with Ethiopian b-roll layered against ethereal chanting and birdsong—a boy drives a donkey cart, pelicans lounge in a scruffy lagoon. The camera pans from a pair of green flip-flops up a long orange skirt, to a teenage girl’s pink-and-white jacket. She strolls away, towards a thatch-fenced village. “My name is Tigist,” she tells us in Amharic.
