Watch: Kim Ok Bin And Lee Joon Hyuk Fight For Survival Against Humanity's Worst Instincts In "Dark Hole" Trailer

OCN’s upcoming drama “Dark Hole” has released its main trailer!

Described as a “mutant survival drama,” “Dark Hole” is about what happens to a group of survivors when humans begin to turn into mutants after breathing in mysterious dark smoke from a sinkhole.

Kim Ok Bin plays Lee Hwa Sun, a police detective in a Seoul regional investigation unit who comes to the town of Mu Ji after receiving a mysterious phone call from her husband’s killer. Lee Joon Hyuk plays Yoo Tae Han, a tow truck driver and a native of Mu Ji.

The teaser opens with a look at Kim Ok Bin standing on the edge of the terrifying new sinkhole that has opened up in the town. Meanwhile, Lee Joon Hyuk is attacked by a mysterious figure while driving around town. After showing a glimpse of the mutant humans transformed by the smoke, Kim Ok Bin observes, “Black eyes and black blood… These aren’t humans.”

A small group of humans fight for survival against the swarms of mutants, but someone says in voice-over, “I’m more scared of humans than mutants.” Someone else shouts, “It’s because of you that we almost died!”, suggesting that the selfish actions and the worst instincts of humans might pose more danger to survival than the mutants themselves.

“Dark Hole” premieres on April 24 at 10:30 p.m. KST and will be available on Viki. Check out the trailer below!
