Eating only the contents of 191 tins of beans over 40 days transforms Beau into The Human Bean, and in doing so gives him a front row seat into how one food, totally and utterly, dictates how he feels.

Epiphanies are had, saddles are blazed, and genuine insight emerges from what is strangely appealing day-to-day of mediocrity.
