In the Native American Red Land tribes, the chiefs received eagle feathers representing the bravery and leadership of the eagle king, who represented their deity. He tied the feathers with the feathers he had received before completing the mission. He walked into his home where his wife had just given birth to a baby boy and named him Yakari. As time went on, his son riding a horse from childhood to adulthood with his friend. And it's time for them to start hunting to become their parents' successors. Yakari, who have close friends Clin, are worried about the journey as they have to complete missions in the village that assigned them. And there are many groups of young people in the village to complete this mission, with one group having two partners. Suddenly, the village chief, Yakari's grandfather, blew smoke as a sign on the cliff for the youth to embark on a mission that saw many eagles in the sky fly up in the air to follow their actions. As Yakari started to get on his horse, he lost his father's knife, which he saw the rooster hide his knife under their body, making his team leave slower than the others.
Yakari and Clin travel to the cliff where their first mission is to bring the goat that climb up to down of cliff. They both really wonder why these goat can go up and can not go down. At that moment, Yakari decided to climb the cliff to retrieve a goat trapped on the cliff. He let Clin told at the location where he had to climb, as he could not look down. Because the rocks are slippery and very steep. When he arrived, he grabbed the goat's leg and tied it behind his back. At that moment, his foot slipped on the wrong rock and almost fell down, but he used the force to catch the rock and came down safely. Clin that stand below watched in horror when she saw Yakari stepping on the wrong rock. When he looked at the goat, he saw that it was a goat's skeleton, and the skeleton melted away, with an eagle echoing its sound with their first mission successful.
At night when they are sleeping, the wolves howl and come out to hunt them under the moonlight. So they used firewood to chase the wolves, with one of the wolves jumping up and biting Clin's arm. And she began to feel cold and sore, so Yakari pulled her to hug after he wrapped her wounds. In the morning, Clin recovered and was able to move on. She starts to feel weird because of Yakari's hugs that she is shy when they are not as young as before. They arrived at a place where large herds of wild horses were grazing. So they had to catch a horse and bring it go back to their village. When they use ropes and tricks to chase a horse that is the strongest. The horse ran back to attack them, and the horse was able to command other horses to surround them as well. It startled their horses awake and made them fall off their backs.
It was about to jump on them and killing both of them, but Clin pulled her leash rope around the horse and jumped on it, with Yakari jumping up behind her and they was able to order the horse to stop roaring and listening them. The other horses, who saw their leader trapped, was running escape this place. The eagle echoed again. They both tied their horses to the ropes with the horses they captured and rode their horses forward to last mission. Arriving at the swing bridge, they saw a group of young people injured by a series of bear attacks on the other side of the road. Therefore, no one can take the plants that grow in the caves where the bears live. Yakari walked to the cave alone when Clin was helping to bandage her village youth warriors team. When Yakari picked the plants, a shadow of a bear stood behind him, pulling his hand up to claw Yakari's back. But he rolled away and it's holding a big rock try to throw on him . He took his knife and stabbed it in the bear's arm, causing it to scream and startle other bears.
Yakari ran back to the swing bridge and cut the rope of the bridge and clung to the broken bridge, making it impossible for the bears to cross to the other side. The youth warriors team and Clin are terrified to think that Yakari fell into the gorge and died. But suddenly saw Yakari cling back up, Clin and a group of men rushed to help him with a full body injury, and the eagle's voice echoed. On the way back, an bad young man stole their plants. When they arrived at the village, they saw that the villagers were waiting for them. The person who stole their plants and traveled to the village before them did not get the eagle's feathers because the eagle knows the whole truth. And that person must be disciplined to be a horse keeper forever. He and Clin get an eagle's feather and become a new generation of village warriors. At night, they had a party and the two of them, who were in love with each other, shook hands, danced and kissed with love. Yakari received many eagles, when he completed many successful missions, he also succeeded his father. Clin, who was teaching her son to ride a pony, was greeted by Yakari, who had just returned from the hunt, he was hugging his wife with nostalgia and watching his son happily ride his pony with his wife.
