'The Blue Door' is built around one of the oldest questions in storytelling: "What if ...?" What if I return home one day to find, behind a familiar door, an unfamiliar world? What if the people closest to me turn out to be strangers? What if strangers start claiming a place in my life I cannot imagine? What if the memories of the most important moments in my life can no longer be trusted? What if I am not who I think I am?
