Peter gets washed away from the beach by a big wave and finds himself stranded on a deserted island. He uses materials he collects like wood, leaves, and string to build shelter and tools to survive. After a restless night dreaming of food, Peter sees a girl fishing in the ocean with his net. Angry, he swims out and retrieves the net. Realizing he needs to get home, Peter builds a boat out of logs and bamboo and paddles for two days, eventually spotting surfers and a beach that signal he has returned home.
