Her father William disapproves of her clothes and friends. William's aggressive attitude has a negative impact upon his daughter's relationship with Brad, the captain of the high school football team. When Jennifer tells Brad that she is unable to attend a concert with him because her father refused to give her permission, Brad decides to break up with her. He feels that William is exerting too much control over the relationship. Although Jennifer is shocked, the fact that Brad chooses to display interest in another girl at school makes her feel even more frustrated.
After meeting Nick Ryan at a gas station, they soon form a close relationship and begin going out with one another. Nick is infamous in his neighborhood for having spent time in jail on an assault charge. When Jennifer's parents decide to spend a weekend away from the house, Jennifer uses this as an opportunity to get closer to Nick. Her parents decide to return early and she is caught in her parents' bed with Nick. William is unable to contain his fury, threatens Nick and chases him out of the house.

Jennifer's mother tells Jennifer that she will no longer protect her from her father, nor take her side.
