Love on the Vines tells the story of Seth Vincent (Steve Talley), who expects to inherit the small, traditional vineyard he runs with a single worker, being virtually adopted by the old founder.
However, Seth can only succeed if his ex Diana Armstrong (Margo Harshman), the late owner's niece, accepts her half and they collaborate until the next harvest, in six weeks.
Diana refuses to play along and sell to Seth, insisting on actually take part in the harvest, meaning he must teach her.
Industrial competitor Grant Gerritson (Jack Wagner) counts on them falling out to buy at least Diana's half above market value.
Manipulative Grant gets Diana's boss (Tom Kirkbride) to offer her a promotion requiring constant travel and sabotages his bright graduate son Paul's (Parker Harris) budding romance with waitress Amelia (Brittany Underwood).
But Paul is no longer prepared to be Grant's luxury puppet.
