To help capture a serial rapist-turned-killer, FBI Special Agent Don Eppes recruits his genius brother Charlie, who uses a mathematical equation to identify the killer's point of origin by working back from the crime scene locations.

Charlie accurately predicts where a band of bank robbers will strike next. But when Don and his team confront them, a massive shoot-out occurs leaving four people, including an officer, dead.
