From a California Christmas ice kingdom, to an underwater holiday mermaid show, to an extravagant festive boat parade, to a turbo-charged manmade Santa-sleigh. Xtreme Xmas takes viewers into America's most unusual, wild, wacky, awe-inspiring and bizarre Christmas celebrations. We'll crisscross the country featuring the men and women who take Christmas celebrations to ultimate heights. We'll dive deep into holiday celebrations unlike any other - featuring a Florida Christmas golf cart parade, a holiday doggie dress-up contest in Conway, South Carolina and an all-night rave in San Francisco aptly titled "the Elf Party" and that's just the beginning. It's Christmas taken to the extreme - It's Xtreme Xmas.
