After a mysterious, deadly snowfall in sunny Buenos Aires, Juan Salvo (Ricardo Darin) and his friends look for answers out of curiosity, as Buenos Aires has only ever seen snowfall thrice in history. Juan Salvo goes looking for his daughter and realizes that this deadly snow kills everything it touches.
Salvo and his friends take it upon themselves to lead a team of individuals to form a resistance against what they suspect is nuclear warfare. The survivors gear up in protective suits and masks as they try to uncover this mystery. However, this proves to be a tough feat, as nobody in the city is willing to trust each other until they get to the bottom of this eerie phenomenon.
As they search for answers, they learn that extraterrestrial forces are invading the Earth by using this toxic snow to wipe out the population in large numbers, eradicating the human race so they can inhabit the planet. The survivors accept they must team up with each other to save themselves and their home.
