Catherine, Sara and Nick investigate when the body of a female prison inmate is found tied to the underside of a bus. What first looks like an escape gone wrong turns out to be a murder when it is discovered the woman was already dead before she was tied to the bus. Meanwhile Grissom and Warrick investigate the death of a man stabbed to death in his apartment.
This is the first time that Catherine give the last few bits of dialog before the opening theme.
Gina Torres made herself a special guest as Warden Hutton in this episode, then she is the wife of Laurence Fishburne who portrays Raymond Langston before going to the half of season nine as a regular cast.
