Netflix has released a full, detailed synopsis for the series:

“In the spring of 1959, thirteen people are stranded in a violent storm on a small island off the coast of Majorca. No one could have imagined what was about to happen at the secluded hotel where they were staying: Elisa Mander, a quiet English tourist, is found dead. What initially appears to be a suicide soon reveals itself to be an even more disturbing murder.

Basil (Jose Coronado), a retired actor who once played Sherlock Holmes on the big screen, unexpectedly finds himself in the role of investigator. As suspicions spread among the guests, including Adela Figueroa (Maria Valverde), a mysterious young woman traveling with a friend, he teams up with Foxa (Martino Rivas), an aspiring thriller writer, to search every corner of the luxurious hotel for answers, while testing the composure of hotel manager Mrs. Auslander (Maribel Verdu).
