Along the way, Dory makes friends: Marlin (voiced by Albert Brooks) and his son Nemo (voiced by Hayden Rolence), whom Dory helped locate when he got lost from his family in "Finding Nemo."
One day, Dory has a flashback that triggers a dim memory of her parents and her origins. As a result, she becomes consumed with trying to find her real family.
Marlin and Nemo join Dory in hitching a ride across the ocean with a group of sea turtles to California, from where Dory is convinced she came. They find themselves in a bay, polluted with trash and debris.
Suddenly, Dory, who has become entangled in a ring of plastic, is plucked out of the water and plonked into a cooler by people in a boat. "No respect for ocean life," one of the people says, as the boat carts Dory off to the Marine Life Institute and deposits her in a tank alone, in a building built just for quarantining wild animals taken from the ocean.
