Halachah. The word is as hard to pronounce as its meaning is to understand. "The way", "the walk" or "the path" all describe what's commonly oversimplified as Jewish "law". Brandon takes a long and winding walk through Brooklyn with an expert on Halachah to understand exactly where it came from and how it was made. A stop into the local matzah bakery shows him that like law, the recipe is ancient, exacting and very much alive.
