The sister, named Leah, has always believed she was the victim of a curse placed on her by their estranged father. She has convinced herself that the curse is the reason why she has never been able to settle down and always ends up in failed relationships. She seeks out the help of her brother, Alex, who is initially skeptical but is eventually convinced to accompany her on a journey to try and break the curse.
Their journey takes them on a road trip across the country where they encounter all sorts of strange and unusual people and situations. They visit psychics, shamans, fortune tellers, and other people who claim to have the power to help break the curse. Along the way, they discover secrets about their family and past that they never knew.
As the trip progresses, Alex begins to doubt the validity of Leah's curse and believes that she may be using it as an excuse for her own personal shortcomings. However, he begins to have second thoughts after witnessing some strange and supernatural events that seem to support Leah's claims.
In the end, they come face to face with their father, who reveals the truth about the curse and why it was placed on Leah. Alex and Leah are able to break the curse and finally put their past to rest. They come to understand that the power to change their lives was within them all along, and that they were able to break the curse by simply believing in themselves.
