Madrid, Spain, June 30th, 2016. Rafael and José Luis jam a crazy one-day trip in search of the city's jazz scene, meeting the musicians, the club owners, the audience, the true believers who tell the story from the beginning, back in the 1950s, until the last breath of this memorable day.
Unfortunately the movie Solo en un día is not yet available on HBO Max.
