Millionaire Thomas Harlow's sudden death leaves his young wife, Grace Olivia, as the sole heiress to his fortune. But there's a catch - she must remarry within a year or risk losing everything to a local dog shelter. And with a deadly cancer diagnosis, Grace's time is running out.

Desperate to save her from financial ruin, the estate lawyer places an ad on a dating site. Suitors flock to Grace's door, but none seem to measure up to her late husband. Little do they know, one man has been quietly watching and waiting for the perfect moment to claim his bride - a man who has been there all along. As the competition dwindles and betrayal lurks around every corner, Grace must rely on her southern charm and wit to navigate through the dangerous game of love and money.
