After a period of study in Europe, Danielle arrives in Bento Gonçalves, Rio Grande do Sul, to teach gastronomy classes. Among her students is the clumsy Luca. As sour as a lemon, the young woman quickly clashes with the sweet-as-honey boy – so sweet it's almost cloying. Days later, the two attend the grape harvest festival. And the attraction, disguised as animosity – amidst the flour fight and pie-in-the-face – blossoms into romance. What Dani doesn't realize is that Luca is a descendant of the Bellini family, an Italian family who established the Mamma Mia Pizzeria in the same alley where the Cassoulet family, the young woman's clan, opened the Bistro Paris. The matriarchs Maria and Françoise were inseparable friends in childhood, but a love rivalry turned them into enemies, making their restaurants the stage for this amusing rivalry.
