A team of FBI agents and their K-9 partners race across the country to track down criminals and save lives.

Guardian - Terri Reed

When a fellow FBI agent is kidnapped and a protected witness vanishes, Leo Gallagher will stop at nothing to find them both. So when he discovers a link between the case and a single mother in Wyoming, Leo and his trusty K-9 partner rush to question Alicia Duncan. Could she be the key to locating the missing persons? Not if a killer has anything to say about it.

Sheriff - Laura Scott

Witnessing a prison break, FBI agent Julianne Martinez is within seconds of death...before she’s rescued by the one man she thought she’d never see again. She’d know her long-ago love, Brody Kenner, anywhere, even with a sheriff star on his chest. But partnering with Julianne to solve two cases only leads to danger when the hunted becomes the hunter. This is a mission that cannot fail...because Brody lost Julianne once, and he won’t lose her again.

Special Agent - Valerie Hansen

When Special Agent in Charge Max West and his K-9 partner, Opal, look into a series of bombings in Northern California, horse trainer Katerina Garwood instantly seems suspicious. As the ex-fiancée of a man tied to the criminal Dupree family, Katerina may know more than she’s letting on — especially since the infamous syndicate is targeting her. With the criminals closing in, Max must separate the truth from lies, or he and Katerina may not live to share tomorrow...
