It is time for Nemo to head to school and his father has brought him to the "bus" stop. He is playing with his friends near the edge of the dropoff when his father tearfully reminds him of its dangers. Nemo's mother was killed here in order to save Nemo from predators. In defiance of his father, Nemo swims over the dropoff to see the boat that is far above him. He is captured and taken away. Nemo's father, Marlin, is desperate to find his son, and enlists the help of Dory to find him. Dory and Marlin travel the ocean in search of Nemo and have a great number of adventures before eventually being reunited with him.
