Angelo sharpens a wooden stick with his knife whilst carefully observing Mario's printing shop. As night falls Mario shuts his shop and walks away and Angelo follows the man in a threatening manner. Visibly perturbed, Mario approaches his building; he is breathless as he enters the house. Angelo stops outside and waits near the main entrance. While Mario has dinner with his family, Angelo leaves for a night club where Laura unknowingly awaits. The two of them dance romantically, unable to conceal their love for each other. The next morning, while Mario goes to work as usual, Angelo awakes to find he is still holding Laura in his arms. The balance has been broken, anything could happen next?
