Just as an expectant Londoner (Jodie Comer) went into labor, the city was pelted with incessant rainfall that flooded Britain's lowlands and triggered a nationwide ecological disaster. As she and her husband (Joel Fry) make a survival dash with their newborn to his parents (Mark Strong, Gina Sosanya), they'll face perhaps more peril from a decaying social fabric than they do from the elements. Mahalia Belo's singular disaster opus also stars Katherine Waterston, Gina McKee, and Benedict Cumberbatch. 102 min. Widescreen; Soundtrack: English. Region Free
