In a drought-ridden desert landscape, Ruth (Gugu Mbatha-Raw) is on the run, hunted by mysterious forces interested in her otherworldly powers over the environment. With nowhere else to go, she flees back to her family and the farmhouse she abandoned long ago. There, while being pursued by the local Sheriff (David Strathairn), she begins to mend the broken relationships with her mother (Lorraine Toussaint) and daughter (Saniyya Sidney) and learns finally how to set her powers free.
