Forgetful blue tang Dory is living happily in the reef with Marlin and Nemo. When Dory suddenly remembers that she has a family out there who may be looking for her, the trio takes off on a life-changing adventure across the ocean to California’s prestigious Marine Life Institute, a rehabilitation center and aquarium. In an effort to find her mom and dad, Dory enlists the help of three of the MLI’s most intriguing residents: Hank, a cantankerous “septopus" who frequently gives employees the slip; Bailey, a beluga whale who is convinced his biological sonar skills are on the fritz; and Destiny, a nearsighted whale shark. Deftly navigating the complex inner workings of the MLI, Dory and her friends discover the magic within their flaws, friendships and family.
