In the beginning you see a woman go into a shower ( not the very beginning) and you see one of her breasts in the shower.

A couple begin to make out ( fully clothed) on a bed furiously, anna then stops for a little bit and goes to a flash back, in the flash back you see again, one of her breasts revealed for a few moments then she goes to back to reality and they begin to make out furiously ( still fully clothed) she than takes off the mans shirt ( all you see is his back) and the scene stops from there.

Anna has another flash back, there is a man pinning her to the bed both fully clothed and the scene lasts for only 3 seconds at the most.

You see anna's boyfriend's throat get cut by a biker and he lays on the ground, coughing up blood, choking and trying to tell anna to run from the guy that cut him.
