Allison's plan is to go to grad school so she can get a good job and care for her schizophrenic mother. When her long-lost father returns, he claims he can bring Alison's mother back from the dark place her mind has gone. She doesn't want to believe his stories about a long forgotten Irish people, the Tuatha de Danaan, but she must work with her father if there is a chance that it could restore her mother's sanity.
