Netflix’s 6-Part Sci-Fi Series Is the Perfect Binge Before Its Bigger and Better Season 2 Return

Netflix gave us some great shows in 2025, but not many of them were as incredible as The Eternaut. This Argentine gem of a series quickly and quietly became one of the streamer’s greatest hits that year. Although it has only six episodes in its first season, The Eternaut is one of the best sci-fi series in recent years and one of Netflix’s boldest projects. Its success has also prompted a quick Season 2 renewal, with the promise of making it even bigger and better.

What Is ‘The Eternaut’ About?

Netflix has made an effort in recent years to expand its catalog with iconic Latin American stories, including productions such as Senna, One Hundred Years of Solitude, and, of course, The Eternaut. The latter was originally a seminal comic book by Héctor Germán Oesterheld and Francisco Solano López, released in 1957, and is one of the defining stories in Argentine culture within the last century.

While the Netflix series makes some changes to the original material to fit the streaming format, the key aspects and plotlines remain intact. The story follows Juan Salvo (Ricardo Darín), a man whose truco night with friends is suddenly interrupted when a mysterious snowfall begins falling over Buenos Aires and killing everyone it directly touches. The only way to leave shelter safely is to completely cover one’s body, leading to the show’s iconic image of Salvo wearing a diving suit to explore his changed surroundings.

Those with enough layers to venture outside also have to deal with giant insect-like beings that are now storming the city streets and attacking survivors. Unfortunately, it gets even worse: some people are also turning on their fellow survivors and allying with the insects, hinting at a coordinated alien invasion. Salvo remains one of the few sane people in this chaos, trying to save his family and friends and make sense of the weird visions he’s been having since it all began.

‘The Eternaut’ Is a Window Into the Darkest Parts of Argentine History

Beneath its outer science fiction layer, The Eternaut‘s story is a sharp critique of fascism and authoritarian regimes. Each stage of the invasion represents different aspects of how oppression gradually takes over, increasing violence and repression until most people are too numb to realize what’s happened. Those who do must band together and resist, as per the show’s logline: “Nadie se salva solo” (“No one is saved alone”).

The Eternaut resonates especially with Argentina’s own troubled past and present, as the comic book was first published when the country was ruled by a military junta following a coup, a time when the opposition was targeted ruthlessly and democratic institutions and policies were openly thwarted. Decades later, another military dictatorship took over during the infamous Dirty War, repeating the cycle, victimizing people such as Oesterheld himself, and leaving scars still visible in Argentine politics and society.

These cycles represent the deep instability and insecurity that Argentina has endured for decades now, both financially and politically. As a country, it has been in a constant state of crisis all this time, and even the most well-meaning of governments usually fail to bring a long-term sense of security to the people. In The Eternaut, that’s represented not only by the successive “waves” in the invasion, but also by the makeshift way people handle it, relying only on each other and things they know for sure work.

Although short, Season 1 of The Eternaut was impactful enough for Netflix to quickly renew it. The series has barely reached the comic book’s halfway mark, with changes being made mostly for the better, adjusting the pacing for the first season’s six-episode structure and introducing new characters and storylines. The season ends at a point when the story is about to expand significantly, with some important Buenos Aires locations set to play key roles as the true nature of the invasion becomes clearer.

This expansion comes at the perfect moment for both the series and Netflix. The streamer’s Vice President for Content for Latin America, Francisco Ramos, has recently shared that “the ambition has gone to a new level” for The Eternaut. Although filming hasn’t begun yet, Season 2 production is already underway and is “way bigger than Season 1, not only in budget, but in terms of scope and conception.” So, if Season 1 was already a remarkable adaptation, expectations for the second are now sky-high.

Getting international stars like Ricardo Darín in front of the cameras can’t be an easy task, given his demand, just like scheduling all the different production stages and making them work continuously also can’t. As Ramos says, production is now focused most on “technical with some VFX conceptualization,” both essential things, considering the new additions for Season 2 go way beyond giant insects. It may take a while, but that means now is the perfect time to catch up with The Eternaut before it returns on Netflix.
