We pick up with Marlin, Nemo and Dory a year after the events of ‘Finding Nemo’ ended. The three have adjusted into a family routine. Although the ever forgetful Dory (Ellen DeGeneres) feels that there’s something missing. When she suddenly starts remembering her childhood, she decides she must go find her parents. Nemo and Marlin accompany her on her quest. Along the way they have some frightening and humorous adventures as they try to find out where Dory belongs.
