When Erin MacKenna's high school canoe float is disrupted by an earthquake separating her group from the main party, she and a younger teen stumble on men burying a murder victim, are kidnapped and held prisoner by known human traffickers, drug dealers and racketeers. Her father, architect Patrick MacKenna, must neglect his earthquake-stricken clients and drop everything to rescue her. He fears Erin, under constant guard and the threat of exploitation and shame, will bond with her captors in a self-imposed prison. For her own secret reason, Erin can't trust him and feels her least risky road to self-preservation is through cooperation with her dreaded captors and reliance on her trusted friends for rescue. Only if she and her young protégé can escape and father and daughter can reconcile will they be able to capture her tormentors and restore order both to their own lives and to their tremor-ravaged city.
