Hyojin Gong, Hyejin Jeon, and Chunhee Lee. Three actors are starting to take small actions for the environment. Being ardent campers, these three have always worried about the environment and they pluck up a little courage to talk about it this time. Their trip to the energy self-supporting island, Jukdo resembles a survival show at first sight but it's also a story of growth wherein they collect ideas through SNS, use their talent as actors to succeed and take initiative to solve problems. As we will see in the packing container episode and the use of ESG strategies, it became a momentum for public corporations to unfold eco friendly projects. Just a little courage achieved more than a little. At the end of the film, we get to see what 'just a little courage' can bring about.
