First non-Japanese film to be produced by Studio Ghibli.
A nameless man set adrift by a storm wakes up on a deserted island. Finding fresh fruit and water, as well as a large variety of animals and a sweeping forest of bamboo, the man decides to leave the island. The man builds a raft from bamboo, and attempts to sail away. However, an unseen animal destroys the raft, forcing the man back to the island. Attempting to escape with another raft, his plan fails again from the unseen animal. Trying a third time, he finds that the animal is in fact a red turtle. His raft being destroyed again, the man retreats back to the island.
