A year has passed since Lise Norwood survived a violent encounter with a serial killer. Thanks to the publicity from that case, her private investigation firm is thriving.

Lise attends the grand opening of a museum's new art exhibition, where she is lauded for locating a long-lost masterpiece. At the same time, an unidentified homeless boy is gruesomely executed in San Marco, Florida. Both events, seemingly unrelated, soon intertwine, and Lise is hired to learn the identity of the victim. Her investigation becomes more perplexing when she discovers that multiple kidnappings, a million-dollar briefcase, and a band of juvenile thieves are tied to the boy's murder.

Unable to turn to the authorities for fear of retribution against innocent victims, Lise relies on old friends and new to assist her investigation. But with multiple lives at stake, Lise will ultimately have to step into the lion's den alone, knowing she's outnumbered and outgunned.
