After Matt and his fiance Jessie are killed in an suicide-bomber explosion in a bar, Matt awakes on a planet where people from every era have been resurrected under the watchful eye of an alien force. With the help of Tomoe Gozen – a 13th century female samurai warrior – and Mark Twain (going under his real name of Samuel Clemens), Matt sets off across the mysterious planet on Clemens’ riverboat, the Not-For-Hire, which seems to run on fusion power. Along the way they encounter Ludwig Durr, the builder of the Hindenberg which also has a mysterious power source.
