Dory is reunited with her friends Nemo and Marlin in the search for answers about her past. What can she remember? Who are her parents? And where did she learn to speak Whale?
Dory, a regal blue tang, gets separated from her parents as a child. As she grows up, Dory attempts to search for them, but gradually forgets them due to her short-term memory loss. In the flashback of the previous film, Finding Nemo, she joins Marlin - a clown-fish looking for his missing son Nemo - after accidentally swimming into him. One year later, Dory is living with Marlin and Nemo on their reef. One day, Dory has a flashback and remembers that she has parents. She decides to look for them, but her memory problem is an obstacle. She eventually remembers that they lived at the Jewel of Morro Bay across the ocean in California, thanks to Nemo mentioning its name.
