Gil Grissom and Sara Sidle come to the aid of a former colleague who is implicated in tampering with evidence. Maxine and the rest of the CSI team work the murder of a couple slain on their wedding day, following the evidence to the salacious underbelly of the Las Vegas elite.

Grissom and Sara's investigation into charges against David Hodges heats up as Internal Affairs joins the hunt. Also, pressure rises for the CSIs when a video game developer's body is found floating in a fountain before a huge gaming tournament.
