"The Wine of Summer" is a story of love, both lost and found, of timeless beauty and the brightness of youth. James (Ethan Peck), at the age of 27, quits his law career in pursuit of his childhood dream of becoming an actor. While studying acting under the tutelage of Shelley (Marcia Gay Harden), he becomes engrossed in Carlo Lucchesi's play, Tinto de Verano, which is set in Spain. James' girlfriend Brit (Kelsey Chow) leaves him, and he spontaneously flies to Spain, where he encounters the misanthropic playwright Lucchesi (Bob E. Wells) at a bookstore in Barcelona. Lucchesi is in a relationship with a much younger woman, Veronica (Elsa Pataky), but still nurtures an old love for his long lost muse, Eliza (Sonia Braga), a novelist, who happens to be visiting her son, Nico (Nicholas Dominic Talvola) a trumpet player who also lives in Barcelona. In the golden backdrop of Spain, these characters find their fates intertwined.
