Gillian Roth finds herself in middle age, living alone, working in a dull job, with few friends and little excitement in her life. So far, so ordinary. 
But Gillian has one extraordinary problem.
Her house is full of other people… people who don't exist. Or do they?
As her surreal home life spirals out of control, Gillian determines to find out the truth and undertakes an investigation into the nature of reality itself.
Will this provide an answer to her dilemma, or will the escalating situation push her over the edge before she has worked out what is really going on?
