[1][2] The films follow the story of Francesca (Frankie) Baldwin and Nate DeLuca from feuding wineries in the town of St. Madeleine, California, as they are thrown together after their past romantic relationship that ended on a sour note.
As their first year at Sorrento Farms is coming to a close, Frankie and Nate are looking forward to debuting their first vintage wine during the town's annual 'Summerfest' celebration.
When the host winery for Summerfest pulls out at the last minute, Nate volunteers Sorrento to replace them, thinking it will be great publicity for their fledgling operation.
Nate proposes to Frankie who happily accepts but they are forced to keep it a secret when Lexie and Marco unexpectedly announce they're marrying on Valentines Day.
Worried about the loan they took to expand Sorrento, Nate and Frankie decide to put any wedding plans on hold as they tend to their vines concerned that they may bud too soon and cause them heavy financial losses.
