After 20 years of marriage, Maria decides to leave her husband. She moves into room 212 at the hotel across the street, with a bird’s-eye view of her apartment, her husband and the life she shared with him. While she wonders if she made the right decision, many of the people in her life offer their opinions on the matter. They intend to let her know, whether she likes it or not, on what proves to be a life-changing evening.
Unfortunately the movie On a Magical Night is not yet available on HBO Max.
