When an actual, honest-to-goodness royal princess runs off from her official obligations and duties for a couple of days to see how the other half lives, she winds up falling for a good Samaritan who is unaware of her real identity during the holiday season. Will her true love still feel the same way once he learns the truth?
Unfortunately the movie Once Upon A Holiday is not yet available on HBO Max.
