Howard (voiced by Chip Zien) lives on Duckworld, a planet inhabited by anthropomorphic ducks. One night, as he reads the latest issue of Playduck Magazine, his armchair begins to quake violently and propels him out of his apartment building and into outer space, where he eventually lands up on Earth, in Cleveland, Ohio. Upon arriving, Howard encounters a woman being attacked by thugs and decides to help her out with his unique brand of “Quack Fu”. After the thugs scamper, the woman introduces herself as Beverly (Lea Thompson), and decides to take Howard to her apartment and let him spend the night. The next day, Beverly takes Howard to a supposed-scientist by the name of Phil Blumburtt (Tim Robbins), whom Beverly hopes can help Howard return to his world. After Phil is revealed to be only a janitor, Howard resigns himself to life on Earth and rejects Beverly’s aid. He soon winds up landing a job cleaning up at a local romantic spa. Due to unfair treatment by his boss, Howard ultimately quits his job and returns to Beverly, who plays in a band called Cherry Bomb.
