About

In the Republic of Korea, the **Marine Special Rescue Unit (MSRU)** exists to respond to extreme maritime disasters. The MSRU is the nation's elite maritime rescue team, selecting only the finest personnel from the Coast Guard, Navy, Special Warfare units, emergency medical services, and diving experts. They are the first to be deployed to sites that ordinary rescue teams find difficult to access, such as typhoons, ship collisions, fires, sinkings, large passenger ship accidents, missing divers, oil spills, and maritime disasters. Maintaining a 24-hour standby system, they continue rescue operations at great risk as long as there is a possibility of even a single survivor. Every member is like family, entrusting their lives to one another in the ocean, and they always carry out their missions with the goal of **"Full Return."**

Intro

Republic of Korea Marine Special Rescue Unit (MSRU).

From sunken ships, typhoons, and maritime fires to crew rescues, drowning accidents, diving rescues, and aerial rescues. The people who rush first to the most dangerous seas.

Someone is waiting for their family, and someone is holding onto their last hope.

So that hope does not fade. Today, they head out to sea once again.

3:12 AM. The black sea looked calm, but a fierce storm was raging beyond the horizon.

The siren wails.

"Emergency rescue request. 42 nautical miles off the South Sea. Fishing vessel capsized. 6 crew members missing."

An emergency alarm rings out in the MSRU situation room.

"All members, deploy immediately."
