El eternauta

Buenos Aires Province, Argentina, 1957. While playing cards on a typical Buenos Aires night, four friends hear a disturbing news report on the radio: a nuclear test in the Pacific Ocean has released radioactive material into the air, which will be carried by the wind toward South America. Seconds later, a fluorescent snowfall begins to blanket the city and its surroundings, killing everything it touches. Is this the beginning of anarchy and violence, or an alien invasion?
