San Francisco, 1880: Jeremy Fantom hates his job as reporter with the Evening Bulletin. He especially hates dealing with riots and rabble rousers like the mayor and Denis Kearney. He dreams of joining a circus or going off to sea. That all changes when he meets Worrell, the strange inventor and his beautiful daughter, Hollyhock. But is that man a genius, or a humbug? And who kidnapped Hollyhock, and why?
