CSI is set to return on Thursday, September 27 with a brand new season with a crossover feature. The third episode, which is entitled "Go to Hell," will feature a Las Vegas forensic team exploring a unique new storyline beginning on that episode. As fans could remember, season 7 revolved around a miniature killer, and this time, season 8 will be focusing on Grissom's enthrallment of the creepy crawly world of bugs.

"Grissom will begin to study colonization in episode three," executive producer Carol Mendelsohn said in a conversation with TV Guide. "We're going to do this very dark, scary episode set in a haunted house. While there, Grissom is going to find a live beehive, and he is going to take this beehive back to [the lab] and he is going to study it all season. He's trying to figure out why these honey bees are dying around the world. It's really about Grissom looking outside the lab… to see the problems of the world. It's Grissom's science experiment for the year."

"Go to Hell" is set to air on Thursday, October 11.

Moreover, the eighth season of CSI promises fans a crossover that has been three years in the making. CSI's Gil Grissom, played by William Peterson and Without a Trace's FBI agent Jack Malone, played by Anthony LaPaglia, will be the ones to cross over. The story will be starting on CSI and end on Without a Trace.

As for the romantic entanglements of Sara and Grissom, Jerry Bruckheimer Television President Jonathan Littman gave a little hint on what's to come for the controversial issue.

"The Sara-Grissom storyline is going to conclude," Littman said. "Don't take it in that definitive term. It's very smartly done."

"We have a big storyline finish at the start of the season," he revealed. "It will play out for a few episodes. The ambition of their [writers'] stories is once again extremely high and extremely quirky. That arc worked so well with Grissom and Sara that we are going to let these characters breathe this year. Everyone has their moments. The characters are going to have their journeys."
