Lockdown

On Jordan Collier's birthday, an unknown 4400 releases a "rage bomb" at NTAC, causing all the male agents to revert to their primal instincts. In order to stop the spread of the behavior, NTAC goes into lockdown, sealing all personnel inside. Now it's up to Diana to find a cure and stop the carnage before it's too late. Meanwhile, Lily suspects the 4400 Center may have nefarious motives toward Isabelle, Shawn adjusts to being the figurehead of the 4400 in the media spotlight, and Kyle finds the prospect of a new romantic relationship.
