After a devastating breakup, instead of drowning in her tears, Amelia Day starts a new business. For a hefty fee, she uses the methods for training foster dogs to transform men into suitable marriage material. Her track record is impeccable until she meets perpetual bachelor Phin Baxtor. From the start, she's confused as to why this guitar-playing hunk would even want to hire her, but she needs the money, so she takes him on. Phin is content with working in his food truck all day and playing the field at night. But his business partner, Jay, offers him a bet he can't refuse. If Phin can complete Amelia's program without changing his ways, he will win Jay's rare guitar. Certain his task will be easier than playing "Hound Dog," he agrees to enter the program. With Phin and Amelia spending all their time together, her techniques begin to slip past his defenses. He might become her biggest success, but falling for a client isn't supposed to be part of the deal.
