His heart is wrenched by the sights he sees as he makes his way through swaying drunken men, ragged match-sellers, Irish flour girls in dirty garments with their bare feet covered in dirt, children with wolfish faces gobbling up decaying food left by the street market.

These are his people and they are dying before his eyes.

This breathtaking musical chronicles the challenging and deeply touching lives of William and Catherine Booth.  Telling of a place where sadness and darkness was common., and how a man saw a need, and set no limits on himself or his God, or what they could accomplish together.
