After a bachelorette party, Jane must defend the bride's fiancé; Kim represents a housewife who claims that her online novel has been plagiarized; a mysterious man appears at the firm; Owen struggles with his new role as Stacy's sperm donor.

When a man is decapitated while doing a daring stunt with his car, the team suspects that it was more than just an accident. During evidence collection, the CSIs enter the world of "sideshows," where kids gather in tricked-out cars, mostly stolen, performing dangerous stunts. However, when Horatio discovers that the victim's car's hydraulics where tampered with, he detects that the accident may be been staged as a diversion to a more serious, yet lucrative, crime.
