Gil Grissom takes over as head of the CSI unit when Brass is transferred to homicide in the aftermath of Holly Gribbs' shooting. With Gribbs in hospital, Grissom brings in Sara Sidle to help investigate the incident, while he and Nick look into the case of a man who killed himself mere hours after winning a fortune on a slot machine.

A quadruple homicide shatters the serenity of a quiet suburban neighbourhood and Grissom's team sets out to discover the motive behind the bizarre murders.

When a rising young Hollywood actress is killed, it appears to be the result of a routine drink-driving collision. However, the CSI team soon suspects that there is more to the case than meets the eye.

After being pulled off the case for strongly disagreeing with the FBI, Grissom secretly works with his team to track down a serial strangler who's paralysed the women of Las Vegas with fear.

When an FBI agent who was working undercover is found brutally murdered in the bathroom of a petrol station, the CSI team are called in to help the victim's partner find the killer.

Nick and Catherine investigate why a woman who was about to be married would take a swan dive from her balcony. Elsewhere, Grissom looks into the brutal murder of a woman found in an alley, but the investigation gets tougher with the discovery that her young child was with her when she was killed.
