Synopsis
'Exactly seventeen steps. Before I knew it, I was standing on the opposite side of the Earth.' While camping, the main character, Ji-suk, discovers a small cave that emanates an eerie energy. Soon after, as he steps out on the other side of the cave, he realizes that he's not in South Korea anymore, but on the opposite side of the Earth- in Colombia. And, in the body of a foreigner named Santiago, someone he’s never met before! Tunda is the story of two young men from South Korea and Colombia whose bodies are swapped through the Cave of God (Cuevas de Dios).
