C. S.I. is an acclaimed, edgy, fast-paced drama series about a passionate team of forensic investigators (among them William Petersen and Marg Helgenberger) who work the graveyard shift at the Las Vegas Criminalistics Bureau.

Between the hidden clues and the buried motives lies the trail to the truth because people lie... but the evidence never does. This box set contains the first 12 episodes from Season 2 of the series.
