How to Deal (2003) (Platinum Series)

Mandy Moore stars as Halley, a young high school student who is disillusioned with love after seeing the many dysfunctional relationships around her. Her father has a pretty new girlfriend who she can't stand. Her mother can't seem to find anyone. Her sister is so dumbstruck with the planning of her marriage that she has become a non-person, and the shallow cheerleaders at her school and their jock boyfriends are beyond comprehension. All these have combined to convince Halley that love is a ridiculous impossibility. But when a tragic event in her life leads to a romantic encounter with a young man, Halley realizes the possibility of true love can sometimes lie in the most unconventional of places.
