The CSIs find blood spatter on the bed sheets and on the ceiling in Harper's bedroom and a fingerprint on the bed. Out of the blue, the power goes out since three generating stations have been blown out by the storm. Nick and Sara follow a trail of blood drops and they find Shelby dead. The CSIs are aware that the life of Harper is in danger and they have a few hours to resolve the case.

"CSI Unplugged" is another good episode of "CSI', with another original story. The plot has many suspects that might be the Harper's abductor and a twist in the end when the identity is finally disclosed. The show is also an opportunity how the cases where investigated a few years before the advance of technology. Every senior professional of technological area has passed through these modifications in his or her career. My vote is six.
