Grissom begins to suffer from hearing loss ("Inside the Box"), as Catherine faces the possibility of losing her daughter ("Lady Heather's Box") during the third season of CSI. Alongside their team, including Sara Sidle, Warrick Brown, Nick Stokes, and Jim Brass, Willows and Grissom investigate the death of a poker player ("Revenge is Best Served Cold"), the evisceration of a cheerleader ("Let the Seller Beware"), a death at a little persons convention ("A Little Murder"), the overdose of a rock-star ("Abra-Cadaver"), a jewelry heist ("Fight Night"), a mob murder ("Blood Lust"), the discovery of a body covered in fire-ants ("Snuff"), and a drive-by shooting ("Random Acts of Violence"). Meanwhile, the team are faced with their own past when they testify in court ("The Accused is Entitled"), Sara struggles to cope with the psychological trauma that she is suffering from being caught up in the explosion ("Play with Fire"), and one of Doc Robbins' autopsies goes awry when the victim wakes up ("Got Murder?").
