The Barbie Museum

Randy Pear is on a race across the US to try and win 2 million dollars. His family doesn't know he's a contestant in this so he's had to drag them along from the casino where the race started. Midway there his daughter, Jillian, spots a roadside sign for a "Barbie Museum" and begs to go. Randy refuses until his wife Bev forces the issue... and to the entire family's horror they find out it's not about the beloved doll, but real life member of the SS Klaus "The Butcher of Lyon" Barbie and the museum is run for and by Neo Nazis.
