When Lieutenant Van Buren discovers a blog site featuring video of an alarming amount of explosives, Detectives Lupo and Bernard race against time to find the anonymous blogger before plans to blow up a school are put into action. The Department of Education's refusal to take the threat seriously and resistance from the teachers' union further complicate the investigation. Fortunately, an administrative assistant at the teachers' union, Alicia (Lindsey Vonn), gives the detectives a tip to lead them in the right direction. Meanwhile, Lieutenant Van Buren struggles to keep her personal issues from becoming public and due to the ignorance of the people possibly revolving around the blogger's terrorist act, they push District Attorney McCoy's buttons.
