Plot:

Surrounded by the immense and furious ocean, a shipwrecked mariner battles for his life with the relentless towering waves. On the brink of demise, eventually, the man will find himself washed ashore on a deserted tropical island of sandy beaches, timid animal inhabitants, and a gracefully swaying bamboo forest. Alone, famished, yet determined to break free from this Eden-like prison, the stranded sailor summons up the strength to build a small raft, and sets off on a perilous journey in the wide open sea; however, an indistinguishable adversary prevents him from escaping. Never giving up hope, each day, the exhausted man attempts to make a new, sturdier, and more improved raft; nevertheless, the sea is vast with wonderful and mysterious creatures, and the island's only red turtle won't let the weary survivor escape that easily. Could this be the heartless enemy?
