Barcelona, late 60’s. Eugenio Jofra, a young jeweler, meets Conchita on a bus. The crush is instantaneous and the two begin the love story of their lives.

When Conchita has to leave Barcelona for two weeks, she convinces Eugenio to carry out the performances on his own. When he returns, Eugenio has become a phenomenon of the city’s underground humor.
