Harvest Season delves into the lives of people who work behind the scenes of the premium California wine industry, during one of the most dramatic grape harvests in recent memory. The film follows the stories of Mexican-American winemakers and migrant workers who are essential to the wine business, yet are rarely recognized for their contributions. Their stories unfold as wildfires ignite in Napa and Sonoma counties, threatening the livelihoods of small farmers and winemakers who are already grappling with a growing labor shortage, shifting immigration policies, and the impacts of a rapidly changing climate.
