Jump. That's what sixteen-year-old P.K. has done. She's taken an impulsive jump from her restrictive life with her family into a life of total adventure: running away to go rock climbing out west with a guy she barely knows. At first everything's amazing. But then she starts to learn more about her companion - and she's not sure she likes what she hears. When the cops finally catch up to them, with an arrest warrant, P.K. has to decide whom to believe: this amazing guy whom she trusts with her life - or the cops, who want her to believe that he may take her life.
