When Kallie Payton applies for a job taking care of a dog named Buttercup on Key West, she has no idea that it's actually a huge Great Dane that's trained to kill. And its owner is no less intimidating - an equally huge and gorgeous man named Brent Shaw who runs a security company named Guard Dog. The chemistry between Kallie and Brent is immediately off the charts, and everything points toward the start of a successful partnership, and maybe more. But when Kallie disappears mysteriously on her way into work, Brent knows that he and Buttercup have to act quickly to protect the woman who's suddenly become his whole world. Can they find her before it's too late?
