In the beginning of the Wild Robot, the robot Roz arrived on an islands'd northern shore. The robot was turned on by curious otters. Once Roz switch turned on she started to explore the island.
One morning Roz was climbing on a mountain and the accident happened. The weather had changed and it started to pour while he was climbing down. Later after the storm passed Roz noticed an egg. Roz cared for the egg and suddenly the egg had hatched. One day Roz goes looking for help on how to take care of goslings. She gets help from all the animals and ends up with a "Nest."
As brightbill grew, he learned new techniques. He learned to fly, swim, and communicate. He even made new friends. One of his friends was called Chitchat. She had this name for a reason. Suddenly Brightbill gets mad at Roz so he goes away.
Roz ended up taking Brightbill to the robot graveyard. But they did not expect to encounter the bears. Which ended up happenng. On their way home a brother bear and a sister bear did not appreciete Roz. So they took off his foot and hurt him. The mama bear stepped outside and the brother bear falls off a cliff but Roz saved him.
The geese were getting ready for migration for the winter. Brightbill feels like he really has to fly south so he does. Brightbill is scared if his mama is going to get hurt while he is gone so ChitChat promises to keep an eye out for Brightbills mama.
The horrible winter had finally gone away. Roz was so excited for Brightbill to return home. But something had happenned before spring started. Roz made a fire for those in the Nest but it ended u attacking them so they made a new lodge. When Brightbill returned everyone was so happy.
