Lucky Girl (also known as My Daughter's Secret Life) is a 2001 Canadian drama film starring Elisha Cuthbert, Sherry Miller, and Charlotte Sullivan, directed by John Fawcett.

Kaitlyn (Elisha Cuthbert) is a high school student whose obsession with gambling leads to her accumulating a mountain of debt.

She steals her mother's credit card, becomes addicted to Internet gambling, neglects her personal appearance and some of her male classmates assault her physically because she did not pay them the money that she had promised.

Once her parents discover the true nature of Kaitlyn's troubles, she is at the point where she is forced by Blair and his wife, Judy, to use her body as a means by which to overcome her debts, just like what they did to Ron.

With the help of Ron, her mother rescues her then bashes Blair across the head twice with a wheellock and Kaitlyn admits to her family how gambling has overtaken her life.

The film ends with the notion that admitting that one has a problem and obtaining help is a very different thing from actually changing one's behaviour.
