They call him "the baby cop"

Ethan Knight, a detective in Desert City, Arizona, believes in putting children first. He's created an unofficial network of foster care for abused and abandoned kids; he's done this by calling on family and circumventing the system to get kids the help they need, when they need it.

They call her "the battle-ax"

Regan Grant is a by-the-book social worker, a woman who doesn't believe in "unofficial." She's the new supervisor at Child Help services, and she's been hired to make sure the rules are followed. All the rules, all the time… The other cops figure that if anyone can persuade her to bend those rules, it's Ethan. If anyone can charm her, it's Ethan. If anyone can make her fall in love, it's Ethan…and four rescued babies.
