A

bomb explodes on a school campus and one girl is killed. Sebastian and his team have to work with a rather aggressive FBI agent on this one, but when the suspect turns out to be just one guy and not a whole terrorist group, the FBI agent leaves. The suspect is a young chemical engineering student who hasn't got any friends and has written letters saying how he'd like his fellow students to die. Danny however thinks this is not the killer and convinces Sebastian, who gives him 24 hours to find a new suspect.
