After Horatio heroically saves Natalia, our CSIs must race against time to find wanted fugitives Jack Toller and Randy North. As the team stages an elaborate trap to lure North from hiding, Toller sells his two remaining engraving plates in exchange for some cash and a young woman he plans on making his next victim. CSIs then capture North and use him to lure out Toller so they can save the girl he plans to kill. But when the setup goes south, and Toller vanishes, the team is forced to reexamine Toller's original case files for any last minute clues to his whereabouts.

A tornado touches down on a murder scene, damaging the evidence and putting Ryan and Walter in grave danger.
