From El Salvador, a journalist contacts the CNI (National Intelligence Center) to provide information about Volkov, a GRU agent who is planning the entry of Russian spies into Spain. But the journalist is kidnapped before he can transmit the information.

At the Center, they've discovered that Elsa has compromising information about Enrique Adaro. Although the journalist wants to publish it, Michelin offers her a deal: she'll collaborate with them by infiltrating the businessman's inner circle.
