As the snow falls in Diamond Springs, the mood shifts, bringing with it a string of suspicious events. The death of deputy David Matthews has Sheriff Sharyn Howard more determined than ever in her quest to find his killer and solve the murder of her own father, the former sheriff. She knows that her old nemesis, Jack Winter, the former DA turned Senator is somehow involved in both murders and she devises her riskiest plan ever to attempt the impossible: bring Jack Winter to justice.
After a young, single mother is run down on a cold winter morning and the murder is traced back to ADA Alan Michaelson, Sharon's suspicions of Jack heighten and the hunt for Michaelson begins. Upon discovering him dead in his garage, slumped over the wheel of his Humvee with the motor running, Sharon puts her plan in full motion.
Regretfully, she has broken off her relationship with her long-time boyfriend Nick Thomopolis, the county coroner, and instead allies herself with her number one target: Jack Winter. Jack's arrogance and unstoppable drive as Senator and the need to control everyone around him makes him more difficult to crack than she first assumed.
With everyone, including her Aunt Selma and most of her deputies, disgusted with her new behavior, the people she loves the most begin to question her capabilities and start to lose trust in the town's most vigilant sheriff. It's up to Sharyn to maintain her beliefs, trust in her own instincts, and get to the bottom of the mysteries that have cast a pall on Diamond Springs for decades.
