A Royal Christmas (2014)

What it's about

A young working girl with a blue-collar background is surprised when her new fiancé announces he is actually a prince of a small sovereign country in Europe. After the couple quickly takes off to spend the holidays at his family’s sprawling, royal castle, she must work hard to win over her disapproving and unaccepting future mother-in-law—the Queen—and find out if love truly can conquer all.
