Plot synopsis
A mixed marriage between Fuchsbau Julie and Löwen Jack attracts P.W.O. activist Blutbaden, led by Darre. The P.W.O. activists slaughter several individuals and kidnap Jack and Julie, then burn then church.

At the Portland Police Bureau, Captain Sean Renard assigns homicide detectives Nick Burkhardt and Hank Griffin to work on this task, noting that it's a "mixed marriage".

Burkhardt and Griffin gain some insight into the situation first from the mother of the bride, then from Nick's reformed Blutbad friend Monroe, a clockmaker.
