Twenty-something slacker Jim Okami's day couldn't get any worse. The Sushi shop's delivery boy lost a tip due to a flat bicycle tire, got dumped by his girlfriend for rich, blonde surfer, and now the entire world is being eaten alive by biologically infected zombies! As Hell breaks loose around him, Jim witnesses the great sushi master Sanjiro, armed only with a vast array of filleting knives, heroically overtaken while defending the strip mall. Like Arthur pulling Excalibur from the stone, Jim instinctively grabs a lone katana honorably stationed above the restaurant's cash register and delivery boy Jim Okami is reborn as Zombie-Sarna! Outfitted with Sanj iro's beloved cash register katana and chain mail armor lifted from a local scuba shop, 'Yo Jimbo!' will set out on a quest to save one small town from the monstrous multitudes of flesh-eating freaks!
