Stephanie Plum (Katherine Heigl), out of work and out of cash, turns in desperation to her disreputable cousin Vinnie, of Vinnie's Bail Bonds, for work. Despite having no equipment, training or particular skill she becomes a bail enforcement agent, chasing after Vinnie's highest stakes bail jumper: Joe Morelli, a former vice cop who is wanted for murder, who also happened to seduce and dump Stephanie back in high school after taking her virginity. In the midst of the chase, Stephanie has to deal with her meddling family, a problematic tendency of witnesses who die when she gets too close, and lessons in bounty hunting from the mysterious Ranger (Daniel Sunjata). When she finally catches up to Morelli, she realizes that the case against him doesn't add up and that the old flame from their school days may just be rekindling.
