It sounds corny, but "How She Move" proves you can't judge a film by its plot line, even if it sounds suspiciously similar to a few other movies about stomping the yard and dreaming your dream and dancing like you mean it.
Since you asked: A bright young woman from a tough urban neighborhood is on the way to academic achievement at a tony private school. Her sister, an addict, overdoses and dies, which brings Raya back to the old, mean neighborhood, where her Jamaican immigrant parents struggle to eke out a living and keep their surviving daughter out of trouble.
To these parents, the local step competitions represent bad elements and trouble incarnate. Not to Raya (played by Rutina Wesley). She joins an all-male step troupe led by Bishop (Dwain Murphy), with whom Raya gets involved in more ways than choreographically. It all comes down to the big step competition in Detroit.
Screenwriter Annmarie Morais, herself a Jamaican immigrant, has a way of making the cliches seem new. Morais made a short documentary about coed step teams called "Steppin to It," and the warmup clearly paid off. She and director Ian Iqbal Rashid, who was born in Tanzania, are following some well-worn narrative paths, but the behavior in the film -- the affections and tensions between parents and children and between dance rivals -- feels urgent and convincing and alive.
