Xabi is a Basque notary who is detected a tumor one day and he realizes that he has very little time to live any longer. After having saved up to a million euros throughout his life, he decides to gain back his old crush, María, whom he met on a COU trip in Benidorm. This marks the beginning of his trip, who arrives to Benidorm overnight, but ends up in a ruinous hotel after realizing that his adventure won't be as easy as he thought. There, he meets Tony, who is excited to get Xabi's fortune and convinces his girlfriend to pretend to be Xabi's childhood crush. Things will take a turn for the funnier when Xabi's friends arrive to Benidorm and realize that he has bought the ram-shackled hotel.
