I'll be home for Christmas

Arthur, who lost contact with his ex and daughter three years ago, works as a hired Santa Claus on Christmas. When he learns that a girl on the list could be his daughter, he takes over the gift giving. His daughter doesn't recognize him, but his ex-girlfriend does. For the evening, both have to put their conflicts aside so as not to ruin their daughter's Christmas - after all, you don't just throw Santa Claus out. - IMDb
