English language film about a prank on a girl on a tourist trip

It is a movie about young adults taking a tourist trip through a major European city, I believe it may have been Paris but I might be wrong, where they go to the underground catacombs of the city and they play a prank on the girl character but in the end the girl discovers the prank and gets angry at them and she kills her former friends.
