Alienoid: The Return to the Future

Ean (KIM Tae-ri) has become trapped in the distant past while trying to prevent the escape of alien prisoners who are locked up in the bodies of humans. She eventually locates the Divine Blade, which can open a door through time, and sets off to find Thunder (KIM Woo-bin) in order to return to the present. Meanwhile Muruk (RYU Jun-yeol), who helps Ean escape various predicaments, is unnerved when he begins sensing the presence of a strange being in his body. Ean and Muruk are pursued by the so-called Sorcerers of Twin Peaks, Madam Black (YUM Jung-ah) and Mr. Blue (JO Woo-jin), who suspect that a monster lies within Muruk; by the warrior Nong-pa (JIN Sun-kyu) who hopes that the Divine Blade can restore his lost eyesight; and by the sinister Jajang (KIM Eui-sung) who seeks the Blade for his own ends.

Back in the present, the release of an alien substance haava by an escaped alien prisoner known as the Controller results in the death of thousands of people. Min Gaelin (LEE Ha-nee) who witnesses this by chance comes to realize that this is only the beginning. With only 48 minutes left before all the haava are set to detonate, the door of time is finally opened and Muruk, Thunder, Mr. Blue and Madam Black are pulled into the present day along with Ean. They must face down the aliens, stop the detonation of the haava and save all of humanity!
