Weeping Willow (S06E10)

After popular video blogger Willow (guest star Michelle Trachtenberg) and her boyfriend Holden are seen kidnapped live on-line by two violent assailants, Detectives Logan (Chris Noth) and Wheeler (Julianne Nicholson) are assigned to the high-profile case. With the help of a tech wizard, the Detectives question whether the kidnapping is staged or real. When a follow-up video blog shows Willow pleading to viewers to download videos which will raise the ransom money, Detective Wheeler takes a trip into cyberspace to face-off with the kidnappers.
