When the Grand Rabbi dies, his son is murdered the same day and suspicion immediately falls on the dead son's brother. The father had to choose one of them to lead the community.
See Fyvush Finkel in a scene stealer as someone in the community who sells religious hats.
Notice how non-Jews and those who left the group, in this case a current police officer, are treated by the community.
In a sidebar story, the former mayor's cocky daughter is arrested for smoking pot and she tries to throw her influence around. Nothing like her father wising up in the end.
