Antonio Castro, Sinatra, is a fighter of life working in an old cabaret in Barcelona imitating Frank Sinatra, accompanied in his show by Groucho Marx, Marlene Dietrich and Lola Flores. But one day, the sky dresses in gray for him; his wife, who works as a waitress in the same place, decides to leave him.

Mario is dominated by his castrating wife, and is also suffering from writer's block. He goes to a local (very mixed) bar where he meets an exhuberant blonde prostitute, through her room mate, a gay gigolo. With Mario's help, the blonde goes on to better jobs in the world of pornography, involving traveling abroad. This may not seem like good news for Mario, but he may also move on to a better phase in his life as a result.

Four friends gather to organize a wild and sleazy bachelor party.
