The main character was an alien Elite Military Officer (Martin Kove) who served in a huge interplanetary war. After the war ended, he was prosecuted for rebellion against the planet's ruling Council; he was found guilty, but in recognition of his valuable services in the war, he was given the chance to reform by spending an undetermined amount of time in a vastly under-powered human form on planet Earth. Along with him was dispatched Control (voiced by Danny Mann), a small floating robot in the form of a mechanical eye with the mission of overseeing Jesse (the earthly name adopted by the alien warrior, from the name tag on the first Earth clothes he wore) to make sure Jesse kept his violent behavior in check. Control also provided comic relief to the series, usually by assessing the events with the catchphrase "Negative outcome. Not good". Each episode followed Jesse as he reluctantly helped different people in need. He derives much of his information from television shows, giving him a skewed sense of Earth culture. At first, Jesse only helped those in need to earn Control's approval in order to put an end to his exile, but he slowly became fond of the goodness he encountered from some of Earth's people.
