Two pretty but ditsy American girls are on a road trip through Europe. In Germany, they end up alone at night and when their car breaks down, they take shelter in an isolated villa. They wake in the morning to find themselves in a makeshift hospital along with a Japanese man. Shit, is this what love feels like?
What movie is that from?
Edit: Found it myself: The Human Centipede (2009)
Also I was surprised to see that this movie got two sequels.
