What Season 4 of CSI: Crime Scene Investigation

The season opens with an investigation that becomes complicated right from the start. Two couples meet at a bar, and soon the team begins to suspect there may be two serial killers. Meanwhile, the CSIs split their attention between parallel cases, such as a house searched after a neighbor's tip or a playground where an outlaw turns up. Grissom, a forensic entomologist of few words, reads each scene through insects and minimal details. Catherine Willows, his right hand and a single mother, brings a police officer's instinct. Every case must be solved with what the criminals leave behind, and the pressure to find the decisive evidence weighs on the whole team. The investigators' personal lives mix with their work in every episode.
