CSI: Crime Scene Investigation Season 1 Episode 23

There's a serial killer on the loose in LA. Since this is a very high-profile case, the sheriff brings in the FBI to help. This annoys Grissom very much as the FBIs like to assume many things while he prefers to let the evidence speak for themselves. Due to his seemingly refusal to cooperate, he is taken off the case. His team, however, knows better and keeps their boss informed on the details.
