Dory is a wide-eyed, blue tang fish who suffers from memory loss every ten seconds or so. The one thing she can remember is that she somehow became separated from her parents as a child. With help from her friends Nemo and Marlin, Dory embarks on an epic adventure to find them. Her journey brings her to the Marine Life Institute, a conservatory that houses diverse ocean species. Dory now knows that her family reunion will only happen if she can save mom and dad from captivity.
