At a Dachshund Derby, quirky Marin McAllister quarrels with uptight accountant, Park Robinson, who disputes her bending of the rules to win the race. Because of their love for dogs in general and dachshunds in particular, they meet at other canine events. Despite their differences, an attraction develops which leads to a first date. Their relationship progresses to intimacy and strong feelings for each other, although both are keeping secrets. Marin, a trust fund baby, was raised in wealth. Park’s family stages Renaissance fairs. When their backgrounds are revealed, her parents delight in their rebel daughter’s staid boyfriend while the Robinsons embrace their son’s free-spirited girlfriend.
When Park says I love you, Marin is reluctant to reciprocate. The men in her past loved her money more than her. Meanwhile, Park volunteers to review the books for her dachshund rescue group. He uncovers an embezzlement scheme her previous accountant missed. To Marin’s dismay, a family member, who did not inherit from a wealthy grandmother, confesses to the theft. When she refuses to tell Park the embezzler’s identity or take legal action, they argue and he cuts off all contact with her.
Two months later, Marin races to save an injured and starving dog. She is shocked to discover it is Park’s beloved dachshund. Then she learns that her ex-lover was shot while walking his dog and left for dead. To rescue the man she loves, Marin initiates a strategy to use dachshunds to heal Park’s mind, body, and heart.
