Paris, 1930. Salvador Dalí and Luis Buñuel are already the main figures of the Surrealist movement.
Unexpectedly, Buñuel is left moneyless after the scandal surrounding his film The Golden Age.
In this difficult situation, he cannot even tackle his next project, a documentary about one of the poorest Spanish regions, Las Hurdes.
However, his good friend, sculptor Ramón Acín, buys a lottery ticket with the promise that, if he wins, he will pay for the film.
Incredibly, luck is on their side.
Reality, memories of his childhood, Salvador Dalí and dreams are mixed in his mind, endangering the film and his friendship with Ramón.
From there will arise the Buñuel of the future. But what is left on the way? How much will that step cost?
