A couple of years after her sister died, Sarah (Sierra McCormick - Christmas in the Heartland), as a legacy, joins her mother's former sorority Psi Kappa-in who are the queens of the campus. It is there she becomes close friends to Daisy (Cassidy Gifford - Like Cats and Dogs), the sororities president, who shows her how the sorority works which rather than being just a sisterhood is more like a business with the sisters whilst acting as sweet as pie are in fact scheming, manipulative, seductive and frequently use blackmail and bribes to get what they want. On learning how much of a monster Daisy is and how once you become a sister you are a Psi Kap for life Daisy must decide whether she is strong enough to get free and take Daisy down.
Once again I find myself feeling a need to say that "Twisted Sisters" is a movie which is similar to many which have gone before but is made for a new generation who will find the attractive cast more appealing than those in previous similar movies. As such whilst "Twisted Sisters", which is also known as "Dark Pledge", is kind of entertaining it is not only made in a style which targets a younger audience but the whole story of Sarah discovering how much of a monster Daisy is and then realising how that now she is in it is hard to get out is a familiar one, covered in one form or another in other movies before.
The thing about "Twisted Sisters" is that it does have this false styling where when ever Sarah is with her sorority friends it is like "Clueless" on steroids with everyone being attractive, well dressed and having high class parties. It is incredibly false and truthfully a little annoying as it tries to be snappy and hip but only ends up coming across as over the top. But despite this the whole story of Sarah realising how evil Daisy is, is an entertaining one mainly because of the evilness of Daisy makes her a good Queen Bitch character.
What this all boils down to is that "Twisted Sisters" is entertaining but it is nothing new with a storyline which has been told in one form or another a few times before. In fact some of the styling might end up being annoying as it relies on over the top acting in a few places.
