Does anyone know how to create this overexposure effect?

Basically I want a character to fire a gun shot, aimed almost at the camera pretty much, and the image to over expose to pure white as it goes through the frames. I can do this by making them image over expose with keyframes. However, if I do that, the whole picture overexposes, where as I want the overexposure to start from the gunshot coming from the barrel, and then spread across the screen as it overexposes to pure white.

But how would I do this in after effects, where you pick a point of origin for the overexposure, and then spread it from there?
