After key evidence is disallowed in a rape and murder trial, the CSI team has only 24 hours to find new clues to nail the suspect.

The team must ascertain whether a fatal rollercoaster accident was deliberate, while Warrick and Catherine investigate the murder of a 13-year-old girl.

Grissom and Sara are called to a crime scene where two bodies have been concealed in pipes at a construction site. Meanwhile, Catherine and Nick investigate a purported hunting accident.

Grissom and Catherine must assemble the pieces of a skeleton apparently cut up with a saw and scattered in the desert. Sara and Warrick investigate the death of a male stripper who died shortly after performing at a bachelorette party.

The CSIs investigate the mysterious disappearance of two boys. Grissom employs the help of the sex offender to put him inside the mind of a paedophile and in turn catch the kidnapper.

When Castle and Beckett find giant footprints at the site of a vicious murder, the team is forced to confront the unlikely theory that Bigfoot is the killer.
