S1E1 The Maid in the Lake

Julio Olmedo, a young man from a modest background, journeys to Cantaloa to see his sister Cristina, who works as a maid at the Gran Hotel. Upon arrival, he receives shocking news: Cristina has been missing for over a month after being dismissed from the hotel due to accusations of theft. Determined to uncover the truth behind her disappearance, Julio decides to stay at the Gran Hotel. Disguising his identity as Cristina's brother, he secures a job as a waiter with the help of Andrés, another hotel employee. During his investigation, he encounters Alicia, a sophisticated woman he had previously met on the train, who happens to be the daughter of Doña Teresa Alarcón, the hotel’s owner.
