When the nerdy Shawna’s long term boyfriend Donovan heartlessly breaks up with her for a prettier and much sexier girl, she is left heartbroken. Wanting revenge against him for breaking her heart, she turns to a secret agency known as Heartbreakers. Rumored to be a group of girls that take revenge against guys that break innocent girls’ hearts, Shawna believes that they can help her. As it would have it, they do exist, and even do an excellent job of getting revenge against her ex-boyfriend for her. So now, Shawna wants in. Not exactly fitting the criteria needed to be a heartbreaker, they style her up and make her beautiful. Then give her first job as part of her initiation. She is on a mission to break the heart of Julian Claire, but Shawna ends up finding out that Julian is a nice guy and his ex-girlfriend was a conniving slut. However, the number one rule all heartbreakers have to follow is NEVER fall in love with a client’s ex-boyfriend.
