Kong Hyo Jin has been friends and camping mates with Lee Chun Hee and Jeon Hae Jin, a married couple, for a long time. They've been striving to protect the environment in their own ways. This time, they gathered to set off on a week-long zero-carbon trip to Jukdo Island. Yoji, Hyo Jin's dog, also accompanies them.
