After his father's mysterious death, Chase Gioberti inherits 50 acres of Tuscany Valley vineyards that his aunt, Falcon Crest winery owner Angela Channing believes rightfully belongs to her.
Angela promises Chase's old friend Paul a large sum of money if he succeeds in getting the Giobertis off their land. But Paul's plan also endangers the Falcon Crest vineyards.
Disenchanted with unruly, irresponsible grandson Lance Cumson, Angela pretends to court Cole as heir to Falcon Crest. Lance bribes Chase's grape pickers not to harvest the Giobertis' crop.
