Headspace is about two brothers whose close proximity to each other causes evil to rise in those around them. Some trick of nature lets them use more of their brains than others do and that seems to cause the manifestations of evil. They get headaches often and don't function very well in society. After their mother goes wacky and is shot by the father, the father gives the boys up for adoption, telling the authorities not to place them together in any foster home. They spend years apart and don't even know each other when the come together. Some doctors try to figure out what's wrong with them to no avail. The movie is made well and the acting is OK, but it just isn't really super scaring or intellectually informative.
