Meet renowned scientist Evelyn Caldwell. She’s highly decorated for the strides she’s made when it comes to genetic replicas and cloning, and has even accomplished creation of replicas. Unfortunately, all is not as well at home—she’s recently discovered that her husband, Nathan, has been having an affair. To make matters worse, the affair is with Evelyn’s own genetically cloned replica. After a morning that begins with a confrontation and ends with Nathan’s body bleeding out on the kitchen floor, the two Caldwell wives will have to think fast—before sharing everything includes sharing a jail cell.
