Finding Dory 4K UHD Blu Ray from DVDLand. The friendly-but-forgetful blue tang fish reunites with her loved ones, and everyone learns a few things about the true meaning of family along the way. Dory (Ellen DeGeneres) is a wide-eyed, blue tang fish who suffers from memory loss every 10 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 mum and dad from captivity.
