Clayderman (Rodrigo de la Serna) is a con man who, together with his wife Verónica (Stephanie Cayo), works onboard the MS Sovereign as a pianist. He uses his position as a crew member to commit petty crimes against the passengers. In Barcelona, Lucas (another scammer) discreetly enters the ship disguised as a crew member. Almost at the same time, Antonio and his family come onboard as regular passengers. Clayderman, Lucas, and Verónica have a past together when they used to "work" as a group, but they split up when both Clayderman and Lucas Love triangle with Verónica.
