Johnny Bravo is walking to the movie theatre on Friday night, looking for a date. He sees several cheerleaders, but as he approaches, they are kidnapped by an evil scientist, intent on world domination. With his Youth-And-Enthusiasm-Sucker-Machine, the evil scientist plans on draining the cheerleaders of their youth and vibrancy, harnessing that power to turn himself into the sexiest man alive. Johnny is insistent that no old, crusty guy is going to end up with all the hot chicks!
