Libero Sbardelloni, newly married, cannot find work in Rome, so he moves to Naples, where Baron Gaetano Gargiulo, his wife Marcella's uncle, lives. The baron, however, is a penniless nobleman who lives by swindling and petty theft, constantly going in and out of prison.
Unfortunately the movie Il furto è l'anima del commercio!?... is not yet available on HBO Max.
