In As Neves, a mountain village, a group of teenagers celebrate a party and eat mushrooms for the first time. The next day they wake up to the news that Paula has disappeared. In addition, a snowstorm leaves the town cut off. It is urgent to find her but no one seems to know anything.
This new adventure of the brothers-in-law begins with the appearance of a corpse right in the middle of the Tui international bridge. This fact comes from what happened a few days ago... Carnival arrives and the Ribeiro family prepares to enjoy the favorite festivities of every good person from Ourense. Two years have passed since the arrest of Alicia Zamora and her Portuguese partner. The brothers-in-law have set up an octopus stand in Ourense, the perfect way to launder the riot money that fell to them from the sky (literally). Between one thing and another, Modesto has become another brother-in-law in the family. The appearance in Ourense of Andreia Nunes (the partner of the detained Portuguese) in search of revenge will complicate things for the brothers-in-law, getting them into a new mess that will turn this Carnival into a real masked ball.
Mabel has gone viral. And in the least desirable way possible. During her flight to Polynesia, she unlocks her sleeping husband's cell phone with innocent intent, but what she finds is proof of infidelity.
Brothers-in-law, Eduardo and Sabonis, married to sisters Cuca and Peque Ribeiro, have made a real mess of one of their business ventures and are in need of money, a lot of money. It will be Sabonis who, in one of his uncontrollable fits of rage, comes up with a plan to fix all their problems in one go: kidnap Modesto, brother-in-law to Alicia Zamora, the businesswoman who screwed them over. There’s just one problem: Alicia has no intention of paying even a penny to get her brother-in-law back. In the end, it will be Modesto himself who comes up with a new plan to help Eduardo and Sabonis get the money they need to save the family wine business. What they don’t know is that police officer Mati, the Ribeiro’s middle sister, is on to their little plan. Eduardo, Sabonis and Modesto have everything to lose, but as Sabonis would say, what could go wrong?
