Meet Burt Hecker: he's a mead-addicted medieval re-enactor from upstate New York who prefers oat gruel to French fries—because potatoes were unavailable in Europe before 1200 A.D.—and is mourning the death of his wife. After an incident involving the police and an illegally borrowed car, Burt is forced to join a local music therapy workshop to manage his anger. With this group, he travels to Germany for a music festival. His real goal, however, is to get to Prague, where his estranged son has been living. Armed with what he thinks is a historically accurate understanding of how to fix the past, Burt sets out on a journey that will change his future.
