Kingdom Season 1

Kingdom tells the story of zombies created from a potion made from a plant called the resurrection plant. When this plant is mixed and applied using a technique similar to acupuncture, it can bring the dead back to life.

The story begins with the death of the King of Joseon from an illness. However, Counselor Cho Hak Ju (Ryu Seung-ryong), the Chairman of the State Council, doesn't want Prince Lee Chang (Ju Ji-hoon) to take the throne. To prevent this, he summons a skilled physician, Lee Seung Hi (Kwom Bum-taek), to "treat" the king's illness.

The doctor uses a potion that can revive the dead. As a result, the King turns into a monster with an insatiable thirst for blood. Unfortunately, when the King drinks the blood of a servant, the servant's corpse is cooked and fed to a starving village. After eating the meat, all the villagers turn into zombies.

Seo Bi (Bae Doo-na), a nurse at the royal clinic, discovers that her superior's treatment has caused a terrible disaster threatening all of Korea. She tries to find a cure amidst the widespread outbreak.
