"Veronica's Room" explores the thin line between fantasy and reality. Students Susan and Larry find themselves lured to an old New England mansion by its caretakers to meet the sole surviving member of the family. They insist that Susan bears a striking resemblance to Veronica, the family member's long-dead sister. They believe her presence will comfort the dementia-afflicted woman and allow her to die in peace. But what begins as a simple errand of mercy quickly spirals into a nightmare cycle of guilt, sacrifice and murder.
