Raised by her grandmother, Meemaw (Lindsay Wagner), after the death of her parents, urban power broker Haley (Laur Allen) hasn't been back to her family's Nashville ranch in years, but is summoned by her brother, Charles (Archie Kao), in a last-ditch effort to save their beloved land from the bank. When she reluctantly arrives just prior to Christmas, her introduction to ranch hand, Kate (Amanda Righetti) goes terribly awry. But now they must put their differences aside and band together to save the homestead... and perhaps discover that finding love isn't always where (or who) you expect.
