When two teenage brothers bungle a bank robbery, their attempt to hide the evidence is witnessed - aurally - by Terrence, a legally blind neighbor. Terrence tells his girlfriend, Nina, and her brother, who then disappears with a handgun. Nina is afraid of what he might do to the brothers. But she also has every reason to fear what the brothers will do to Terrence.

Flash ingeniously interweaves the stories of two who are hellbent on a destructive path, two who stand in their way, and one whose actions may be the spark to set the whole thing off.
