María and Manuel live a completely monotonous and boring life, and they need money to fulfil a long-postponed wish. On New Year's Eve, they visit Manuel's sister and her partner, who are ontological coaches living a lifestyle completely opposite to that of the protagonists: they are adventurous, modern, and charismatic. They lead a community of young people who follow a spiritual doctrine that believes any goal is achievable, even if moral boundaries must be crossed.
