What Happened at the End of 'All of Us Are Dead'—And What It Means for Season 2

The last two words spoken in the final scene of the dramatic conclusion of All of Us Are Dead—"They're back"—has left the door wide open for a subsequent season of the transfixing new Netflix K-drama.

The gripping Korean zombie thriller topped Netflix's global top 10 television series ranking for the 11th consecutive day on February 8, according to data from Flixpatrol, South Korea's The Chosun Ilbo reported Wednesday.

The series sees a group of students attempt to survive a zombie apocalypse while trapped inside a school.

Facing a devastating reality after a long-awaited rescue mission to save them from the rooftop of the school is aborted by the government due to the possibility of the students being infected with the zombie virus, the teenagers are left to fight for their own survival.

What Happened At the End of All Of Us Are Dead?

Following a martial law ruling over the city of Hyosan, the military commander ordered a bombing over the city, including the school, in a bid to prevent the outbreak from spreading to the rest of the country (even if that might mean killing off potentially thousands of uninfected residents who have yet be rescued).

Upon hearing the final warnings for evacuation, the students had no other choice but to run across the zombie-infested school grounds to avoid obliteration. They managed to escape to a forested area behind, and survive the bombing from a distance.

Following the tragic loss of more friends along the way, the remaining students stumbled upon a military rescue team while running through the scorched streets of the city. The kids were then brought to a quarantine camp to join other survivors.

Breaching the curfew in place at the camp from 12 a.m. to 6 a.m., the students come together to investigate the burnt down school after one of them (On-jo, played by Park Ji-hu) sees a distant glowing light at the rooftop of the building from a mountaintop overlooking the school.

On-jo believes the glow could be from a campfire created by Nam-ra (played by Cho Yi-hyun), who disappeared while on the run after escaping the school.

Also known as "Prez" (the class president), Nam-ra appears to be "immune" to the virus but still possesses zombie-like qualities, such as an unbearable hunger for blood. Not quite a full zombie nor a human anymore, she later runs away from the other students and could not be found.

As the students reach the rooftop, they discover the campfire burning and are shocked to see Nam-ra appear out of a dark corner, saying she had missed them and wanted to go see them at the camp but felt she shouldn't due to her condition.

When On-jo asked Nam-ra to go back to the camp with them, Nam-ra replied: "I still have some things left to do here," revealing she'd come across others who are like her. She said "some already fled outside the school but there are still a few left."

Then suddenly, appearing to hear something in the distance that's inaudible to the rest, Nam-ra said: "They're back," before charging towards the edge of the rooftop and jumping off the building with no hesitation.

Stunned and shell-shocked, the students are seen watching Nam-ra mysteriously disappear into the abyss as the final scene fades out.

What This Means for Season 2 of All of Us Are Dead

The show's heavily open-ended finale raises several burning questions, which could potentially be answered in a second (and possibly even third) season of All of Us Are Dead.

While more episodes have yet to be officially confirmed, the director of the series, J.Q. Lee (also known as Lee Jae-kyoo) said that if there were to be a second season, the story could center around a battle between the zombies, he told Korean media on Monday.

The first season revealed there are three types of zombies (at least so far), including two "mutant zombies," as described by Lee.

In addition to "immune" mutant zombies (such as Nam-ra), there are also "immortal" mutants, such as Gwi-nam (a villain character played by Yoo In-soo) and Eun-ji (a student played by Oh Hye-soo, who is bullied by Gwi-nam and others).

These immortal zombies retain at least some of their human qualities, including a heartbeat, a conscious mind and an unstoppable drive for revenge, as played out in the series by Gwi-nam and Eun-ji.

The second season could potentially see a battle unravel among the immune, the immortals and the rest of the zombies, according to the series' director.

Lee explained: "If Season 1 was about the survival of mankind, then Season 2 would be about the survival of the zombies," reported South Korea's NewsPim.

As indicated by Nam-ra in the final scene, there are other immune zombies out there. Season 2 could perhaps see her lead this pack in a battle against the other zombies who pose a threat to the rest of mankind.

Lee also dished on the potential plot of a third season, which could follow a "grand world war type concept," according to NewsPim.

Perhaps the third season will see the final battle between humans and zombies to end the outbreak once and for all.

While neither a second or third season has yet to be officially announced, Lee told South Korea's HuffPost and other Korean media that he hopes there's more to come if fans continue loving the series, which shows no signs of slowing down.

According to Variety, All of Us Are Dead is now the fifth most popular non-English series debut, based on hours viewed in their first 28 days on the streamer, with Squid Game, Netflix's biggest show of all time, still reigning at the top of this list.

Last week, on February 4, the show topped Netflix's U.S. ranking, thus becoming the second non-English series to reach the position after Squid Game.

All of Us Are Dead is available to stream now on Netflix.
