Achilles, a Hulot-like factotum for an evening newspaper, travels around looking for a scoop in the Milan of the "economic miracle."

In the figure of Ettore Zambrini, a small industrialist with a dream of opening a factory overlooking the Autostrada del Sole, Montaldo offers us an effective narrative transposition of the 'animal spirits' that governed the economic boom in Italy at the time. He is a character of contradictory humanity: capable of handling business, overdue bills, trade union relations, marital betrayal, but also the passion that binds him to his wife with equal unscrupulousness.
