At the start of "California Roll", Wine is feeling his age and recovering from a mid-life crisis when he is invited to Silicon Valley by Alex Wiznitsky, a young genius known as the Wiz, who wants him to become head of security for Tulip, a computer company that rose from backstreet obscurity into the Fortune 500 in only three years. Soon after, one of the Wiz's collaborators, another genius known as the Last Nerd, has disappeared. Wine eventually follows the case to Japan where roughly half the story takes place.
