[1] Stefano, a naval officer for some time not operating on ships following a removal and therefore seconded to a Ministry, is warned that his wife Elena secretly transmits military designs and projects that he guarded to foreign powers.

The wife is warned by an accomplice and prepares to leave: she greets her son in tears and begins to pack the bags.

But this acquittal, instead of benefiting him, disfavors him: his relatives turn against him, preventing him from seeing his son, and the Ministry of the Navy requires him to resign.

One evening he meets a prostitute, Wanda, who lends him money: the officer, now on the verge of desperation, tries his luck at the game and fate hangs on his side: he wins a large sum and, having landed in the business field, carries out the right investments becoming very rich, enough to convince Wanda to live with him.

The father tearfully greets his novice sailor son aboard the ship, now reconciled, while Wanda, in order not to get in the way of her career, is forced to leave that cohabitation.
