In the oceanside village of Iyi, the revered Mama Efe (Rita Edochie) acts as an intermediary between the people and the all-powerful water deity Mami Wata. But when a young boy is lost to a virus, Efe's devoted daughter Zinwe (Uzoamaka Aniunoh) and skeptical protégé Prisca (Evelyne Ily Juhen) warn Efe about unrest among the villagers. With the sudden arrival of a mysterious rebel deserter named Jasper (Emeka Amakeze), a conflict erupts, leading to a violent clash of ideologies and a crisis of faith for the people of Iyi. - C.J. "Fiery" Obasi's potent modern fable deploys vivid monochromatic black-and-white cinematography, rich sound design, and a hypnotic score in a folk-futurist style both earthy and otherworldly. Obasi depicts a pitched battle between opportunistic militants promising technological progress and a matriarchal spiritual order living in fragile harmony with the ocean. MAMI WATA transports us to a place that seems both suspended in time and perhaps running out of time, as the threats of modern life wash up on it's shores.
