After all the bodies of water on Earth have mysteriously dried up, Rom, an autonomous vacuum cleaner, must rely on his owner, a man named Eddy, to keep his batteries charged and his dust tray empty, as they brave the harsh Nebraska Wasteland. Unfortunately for Rom, Eddy is an extreme shut-in that’s terrified of the outside world. During their journey, they’ll encounter vast dangers, from man-eating chihuahuas to crazy doomsday-preppers. With only a short period of time before there’s no water left on Earth, through their mutual reliance on each other, the two of them must figure out a way to survive, as the end of all life is near.
