在美國小鎮一家超市的付款通道中，一個黑人對一個10歲白人小孩（JacksonRobert Scott飾）微笑，不曾想，這個善意的舉動受到誤解，引發了幫派之間的對抗，並以驚人的結局收尾。

A small supermarket in a blue collar town, a black man smiles at a 10 year old white boy across the checkout aisle. This innocuous moment sends two gangs into a ruthless war that ends with a shocking backlash.
