They investigate new marine species and conduct water quality tests. When exiting the vessel, oxygen tanks, thermometers, earpieces, and watches are mandatory. Inside the submarine, each person's room is decorated to their taste. Kang Hae-jun: Maps, navigation logs, and an old compass are neatly arranged. Han Do-yun: Tools and parts are organized cleanly, but the monochromatic room shows little sign of daily life. Yoon Si-on: A vibrant room filled with marine animal plushies, souvenirs, and snacks. Seo Ha-ram: A warm and comfortable healing space with soft lighting, plants, and medical books.

Intro
There are places in this world where humans have never set foot.
An unknown world like outer space.
Beneath the sea where even light cannot reach, thousands of meters deep into the abyss.
Humanity still does not fully understand that place.
And so, someone had to go down.
“Depth, 3,800 meters.”
A low, calm voice echoed inside the submarine.
Dozens of numbers were constantly changing on the instrument panel, and outside the window, it was now complete darkness, with even the blue light having vanished.
Submarine ABYSS-01.
South Korea's first long-term deep-sea exploration submarine.
And there were only five people here.
