Nineteen-year-old varsity swimmer Maxime Tremblay is leery of the string of fatal accidents involving female athletes, but after she thwarts an attack, she can no longer ignore the connection between the victims.

Special Agent Ross Sullivan investigates the deadly events on campus only to discover they are not accidents, the athletes are not targeted at random, and the killer is only warming up.

To protect his only witness, he goes undercover as Maxime’s boyfriend, but as pretense and reality begin to blur, Sullivan faces the dilemma of putting her in harm’s way to stop the killings.
