Sam figures out the identity of the so-called 'venom killer' as Robin Poole when a victim, suffering from sea wasp jellyfish stings, disappears from the hospital and it was Robin impersonating a victim. John and Cooper travel to Arkansas to investigate Robin's origins for her murderous lifestyle. Bailey takes drastic measures to curb the carousing Frances by deciding to send to a reform school, in which she shoots him with his own gun. John debates the future of his intimate relationship with Angel and they both agree to split up. After a few taunts, Jack strikes again, first by framing the FBI and VCTF by impersonating an agent and beating up a few suspects, and then abducts both Sam and the 'venom killer' Robin Poole, and taunts the VCTF by filming it on an Internet web site.
