The PJ discovers that Marta is the queen of alternative and sadomasochistic sex in the Algarve and only receives select guests, usually very wealthy or very powerful, but Abel is a regular visitor. However, Abel also appears to be involved in multiple local businesses, including a large enterprise about which little information is available. The PJ pursues a line of investigation that points to Marta as responsible for Abel's death, leaving aside the business, as it is not in the region's interest and there is no indication of any connection between sadomasochistic experiences and real estate deals.

At Abel's funeral, Marta's presence deeply disturbs Ana Cristina. But Ana Cristina's concerns quickly change... the PJ seeks out Zé Maria for questioning. His testimony raises suspicions about his alibi, but also opens another line of investigation: Abel was part of a real estate project on the Island. The inspectors' opinions are divided between the money trail and the sex trail. Marta provokes Ernesto, and Ana Cristina becomes jealous, while Deolinda warns Ernesto that she is dangerous. The project for the Island is blocked by Zé Maria's intransigence, while João Seabra tries to convince Ana Cristina, but, as a staunch environmentalist, he is unsuccessful and is forced to take a different path.
