Walter is selfish, greedy and ruthless, often abusing Francesca, making her miserable. In the end, Francesca decided to run away from him and go to the Boliu River to find his own way. In the Bo River, Francesca meets her colleague Hillvana (Shawana Mangano Silvana Mangano), who has a handsome appearance and haughty personality, and secretly identifies Francesca as a competitor. Walter followed Francesca's trail to the Boliu River, where he was attracted by Sylvana's beauty and launched a passionate attack on her. It turned out that Walter wanted to use Sylvana's position to steal food from the camp. Francesca did everything he could to remind Sylvana, but the latter did not believe her.
