The story in this book concerns the life of Firmian Stanislaus Siebenkäs and is told in a comedic style. Unhappily married, Siebenkäs goes to consult his friend, Leibgeber, who, in reality, is his alter ego, or Doppelgänger (a word of Jean Paul's own invention). Leibgeber convinces Siebenkäs to fake his own death, in order to begin a new life. Siebenkäs takes the advice of his alter ego, and soon meets the beautiful Natalie. The two fall in love; hence, the "wedding after death" noted in the title.
