Synopsis:

Rome 1921. After service, Ulisse and Turiddu decide to stay in the great city and sign up only to be tasked with discovering where certain anti-fascist leaflets are being printed. Having infiltrated the printers Olinto & Figli, Ulisse realizes they are a good family although in league with a group of anarchists, and does nothing about it, since politics fail to interest him in truth. But then he is forced to pass as an anarchist and carry out an attempt. The plan however falls through and all are arrested, but our hero escapes and maintaining his promise goes to carry out the attempt. Naturally he dislikes violence and so his bombs are made of... cauliflower! But things get complicated when two real terrorists arrive and Ulisse has his hands full. Things turn out well, the bombs go off without damage but Ulisse ends up back in prison.
