This weekend there’s a new apocalypse in town with the return of Kingdom. Netflix’s first Korean original follows the story of a prince caught in the middle of a government coup and a whole bunch of malnourished zombies. And it’s finally back with six more episodes.

Written by Kim Eun-hee and directed by Kim Seong-hun, Kingdom is based on the webcomic series The Kingdom of the Gods. The fantasy horror thriller takes place after the Japanese invasions of Korea in the Joseon period, roughly around the 1590s. Equally gut-wrenching and politically enthralling, Kingdom is an addicting tale of corruption. But if you need some help remembering where Season 1 left everyone, don’t worry. We have your back.

…But before we get into zombies we need to talk politics. Kingdom Season 1 revolved around a feud between the Haewon Cho Clan and seemingly the rest of South Korea. The Clan had almost complete political control of the country during this time thanks to some dirty political maneuvering. No one was particularly a fan of Chief State Councilor Cho Hak-Ju (Ryu Seung-ryong) and his daughter the Queen Consort Cho (Kim Hye-jun), least of all a group of Confucian scholars. Integral to this society, the scholars hated Councilor Cho for his and his Royal Army’s indifference to the poor and love of war. The feeling was mutual, by the way. Councilor Cho hated the scholars for undermining his many war-filled plans.

There was a lot of turmoil and Kingdom‘s hero, Crown Prince Lee Chang (Ju Ji-hoon) was caught in the middle of it all. Though he’s technically royalty, Prince Chang had several reasons to worry about his crown, the first being his birthright. Since Prince Chang is the son of a concubine and the mysterious and unseen King (we’ll get back to him in a second), he has no legitimate claim to the throne. As long as no other male heir is born, the prince can keep princing. But once the pregnant Queen Cho gives birth to a son, his time in the sun is over. Prince Chang understood the stakes of his crown and aligned himself with the scholars.

Naturally that made Prince Chang the sworn enemy of Councilor Cho. To escape the Royal Army’s wrath and hopefully overthrow his own father, Prince Chang and his second-in-command fled to an impoverished city. There was just a slight problem with their plan. That city and most of the squalor-marred towns surrounding it had been overrun by a disease that turns people into undead, cannibalistic monsters.

But sometimes there are major benefits to slumming it. While pretending to be poor and searching for an answer to this horrific disease, Prince Chang learned of royal physician Lee Seung-Hui. According to the Royal Court, the King was quarantined for smallpox. That’s why no one saw him and why Councilor Cho had been allowed to rule. As Lee Seung-Hui revealed, that was all a lie.

In reality the king died. The royal physicians weren’t called in by Councilor and Queen Cho to cure him; they were asked to bring him back to life. In attempt to cure him, the King was given the “resurrection plant,” which can only be found in the Frozen Valley. It worked… sort of. The King returned to life but only as an undead cannibal hellbent on eating everyone in sight. You know, typical ruler things.

Finding out that your dad is Patient Zero is never a good day. But adding to Prince Chang’s stress, the towns he and his companions used as shelter become more dangerous. Turns out the military was more interested in keeping the zombies out of the capitol than actually saving civilians. In a brutal display of power, Councilor-turned-Lord Cho ordered for the country to seal off its southern borders, saving the north from the zombie threat and leaving the south to rot.

But those travesties barely touched the peak of Prince Cho’s worries. After reuniting with his old mentor Lord Ahn Hyeo, Prince Cho realized that this plague had happened before. It was something Lord Ahn experienced, though he never directly revealed the horrors to his mentee. And Prince Cho’s time as a dead man walking officially runs out after Queen Cho gives birth. Though she gave birth to a baby girl, a baby boy appeared on her lap. It seems like the crown will do anything to get rid of Prince Chang, even recruit a fake male heir. Speaking of fakes, it’s also revealed that one of Prince Chang’s allies it actually a mole for Lord Cho. The only question is who.

Season 1 ended with Lord Cho marching off to confront Prince Chang for what is sure to be a brutal showdown. But it Kingdom ended with one more chilling revelation.

All throughout Kingdom‘s first season it’s explained that zombies only attack at night because they’re afraid of the sun. But a trip to the Frozen Valley uncovers the truth. Zombies can bear the sun just fine. They just can’t handle the heat. With winter on the horizon and Lord Cho desperate for a face-off, Kingdom is about to heat up in the cool weather.
