Tough-as-nails defense attorney Josie Galloway has one hot button, and FBI agent Locke Harper just pushed it. He dared interrogate her sainted grandmother about an unsolved jewel heist. To her relief, Grandma is just a witness, not a suspected villain. And Locke seems to be the real victim of all this, since Grandma is clearly up to her old matchmaking tricks. To appease the old woman, and maybe salvage something out of an awkward situation, Locke and Josie make a deal. They'll pretend they're falling for each other, earn Grandma's trust, get the answers Locke needs to solve the crime, and Grandma gets the reward money. Case solved, everybody wins. But when Josie and Locke head to the scene of the crime, a honeymoon resort on the coast, they find themselves getting a little too caught up in the risqué fun. Until the very real possibility that Grandma's not quite so innocent snaps them back to reality.
