At the beginning a girl is riding in a car with a guy through the city. I think it was a convertible. They come to a stop and theres a nun standing on the side of the road and they pick her up. She doesn't speak at all. Later the girl sleeps with the guy and then she starts seeing the nuns everywhere. I think she finds out that this guy has slept with all the nuns shes seeing. At the end of the movie another girl is riding in the car with the same guy and they stop and pick up a nun, who is the girl from the beginning of the movie. Cant remember the name to save my life. Any suggestions would be helpful. Thanks.
