The seventh season of CSI: Crime Scene Investigation is as solid as any of the series' previous years. The stories are strong, the actors share potent chemistry, and the characters are believable because they are flawed human beings. This year, CSI delves into the complicated romance between head investigator Gil Grissom (William Petersen) and his underling Sara Sidle (Jorga Fox). The two are reticent to let their colleagues in on their relationship, and the season finale offers a gasp-inducing prospect of their future together. Earlier on, though, there's even a bit of a triangle when Sara learns about Gil's prior romance with dominatrix Lady Heather (Melinda Clarke). The normally steely Catherine Willows (Marg Helgenberger) faces her own dilemmas when she wakes up in a motel room, unsure if she has been sexually assaulted. And fellow CSI Greg Sanders (Eric Szmanda) finds himself the victim of a gang beating after he witnesses a brutal attack... (7 Disc) Production Year: 2008 Starring: William L. Petersen ; Marg Helgenberger ; Jorja Fox ; Eric Szmanda
