CBS last week premiered a sneak peak at CSI's last four episodes of the season, including this week's new "Committed".

In this episode, a brutal murder at a state mental hospital puts Grissom and Sara on a dangerous investigation at a place where only a handful of residents and staff could be responsible for the killing. Meanwhile, Catherine and her team look into the death of young man whose body was found in a crop circle and shows no outward or inward signs of what killed him. "Committed" was written by Sarah Goldfinger & Uttam Narsu, and directed by Richard J. Lewis.

The 30-second trailer for the episode is now available on the official CBS site. For those of you with slower connections, here's a transcript:
