Even in the most dire circumstances imaginable, a single act of kindness can change a life forever and, with it, the lives of countless others. Steve Ross is living proof. The founder of the New England Holocaust Memorial is the subject of this documentary chronicling his life, his time in concentration camps and his search for an American soldier that gave him food and showed him kindness when he was liberated.

Watch Etched in Glass: The Legacy of Steve Ross, tonight at 9pm on GBH 2.
