Bored with his everyday life working in Ducklair Tower as a security guard and sick of being put upon by his girlfriend Daisy, three nephews and Uncle Scrooge McDuck, Donald Duck makes a wish to become a superhero. Unbeknown to him, someone is listening. Computer One--a super-computer hidden in the tower--enrols Donald as the new Superhero of the Future: PK. PK discovers that an evil race called the Evronians plan to secretly invade Earth and to transform its inhabitants into slaves, the "CoolFlames". PK's mission becomes clear: he must use his brand new powers to rescue the Evronians' hostages and save the earth.
