Ashley was spending the weekend in Vegas, where she met the most beautiful boy. Things went fast and not knowing anything about him, she ends up having a one night stand with him. Ashley was supposed to go home and completely forget about him. After all, what happens in Vegas, stays in Vegas... But things didn't work out like that. That beautiful boy she slept with turned out to be her mom's new husband's son.... Her step brother. They know it's wrong and absolutely forbidden, but love isn't always pretty. Will they be able to stay away from each other and act like normal siblings in front of everyone, when they both know deep inside neither one thinks of the other as a sibling?
