When Don and his team attempt to catch a pair of repeat bank robbers in Los Angeles, Charlie devises an equation using probability and statistical analysis to pinpoint the location of their next robbery. Although his prediction for the next robbery is correct, his mathematical model turns out to be useless when the robber’s true motives are revealed.

As the team meets with the executed killer’s ex wife in a search for suspects, the UnSub begins to escalate his plan.
