After Doraemon and Dorami fall out over Doraemon stealing her melon bread, she returns to the future. She finds out that all the robots in the future world have been infected with a virus from a Dracula robot a scientist created and all humans have been placed in captivity. However, it is too late and Sewashi is unable to do anything - she herself has been infected by Dracula, too. Serving as Dracula's minion, Dorami is sent back to the present to bring Doraemon - who is the last normal robot in the world - to him. With Dorami hot on Doraemon's heels, he and the rest of the gang must travel to the future to rescue her from Dracula's curse and bring everyone's memories back.
