Hurricane Harvey is about to hit Houston. Meanwhile, single mom Jia Shah is already having a rough week: her 12-year-old son, Ishaan, has just been suspended from school for getting in a fight. And now their apartment complex is under a mandatory evacuation order. Jia’s sister, Seema, has invited them to hunker down in her fancy house in Sugar Land. Despite Jia’s misgivings --- Seema’s husband, Vipul, has been just a little too friendly with her lately --- she concedes it’s probably the best place to keep Ishaan safe during the hurricane. With Jia’s philandering ex scrutinizing her every move, all too eager to snatch back custody of Ishaan, she can’t afford to make a mistake. When Vipul’s brother and his wife show up on Seema’s doorstep, it’s a recipe for disaster. As the storm escalates, tensions rise quickly, and soon someone is dead. Was it a horrible accident, or is there a murderer in their midst?
