Molecular gastronomist Marcel Vigneron is hired to create an unforgettable engagement party for high school sweethearts, Gregg and Karen, who are reunited after 30 years. With only a few days to pull off an amazing experience at the stunning Church Estate Vineyards in Malibu, Marcel sets out to create an ambitious menu inspired by the couple's love story. The clock is ticking and the pressure is on as Marcel and his team experiment in his test kitchen to make the menu come to life. Marcel tackles 'form mimicking' when he attempts to transform watermelon into ahi tuna for a truly distinctive hearts of palm salad. Other items on the menu include a surf and turf trio, noodles made solely from red wine and edible engagement rings. As the party approaches, Marcel engages in a power struggle with the demanding party planner, Summer, leaving everyone to wonder, who will come out on top?
