In Buenos Aires, a mysterious snowfall occurs one night, quickly killing most of the population. Juan Salvo and his friends are among the thousands who survive, but in the aftermath, life is a struggle.
Salvo braves a ravaged Buenos Aires to reach Elena and Clara's apartment, discovering that human survival instincts can be as deadly as the toxic snow.
Searching Clara's school for clues, Juan and Elena meet Pablo, a student in distress. Meanwhile, Tano attempts radio contact as Juan's visions intensify.
Tano and Juan head downtown, where they encounter a barricade and army forces. Confronted by a sudden threat, they receive help from an unexpected lot.
