When well-to-do couple Daniela (Talancón) and Emiliano (Martínez) throw a birthday party for their young boy, Rodrigo, everything seems to be going smoothly. Rodrigo and his friends are playing, their parents are getting to know one another a bit better (whether they want to is another story), and the weather is just about perfect. That is, until the wind unexpectedly picks up, leading to a horrific accident that kills three children. As they deal with the aftermath, the parents throw blame around at themselves and others: Emiliano was on a business call when it happened — was he negligent? His family’s housekeeper, Moncho (Palacios), was sneaking alcohol during the party — could he have caused this? As the incident rocks the community, everyone grapples with who’s really at fault.
