Timmy is sick and tired of Vicky being mean to him, so he gets revenge by reading her diary and makes Vicky reveal all of her dark secrets in front of a boy she likes, causing him to go out with another girl. Vicky becomes miserable and there is more trouble with Timmy's new and more evil babysitter. Timmy then tries to reverse this so they can get back together.
