Plot
Riley Adams leaves the CSI team in turmoil, as Catherine's leadership skills are called into question ("Family Affair"), during the 10th season of CSI. The team, including the newly returned Sara Sidle, continue to investigate the gruesome, the premeditated, and the unusual, including the death of a porn producer ("Ghost Town"), a botched robbery ("Working Stiffs"), a cop-on-cop homicide ("Coup de Grace"), the murder of a football coach ("Blood Sport"), a bizarre revenge plot ("Death & The Maiden"), a death at a bowling tournament ("Lover's Lanes"), and a human trafficking case that leads Ray to both New York and Miami ("The Lost Girls"). Meanwhile, Nick, Greg, and Hodges celebrate Henry's birthday ("Appendicitement") as Catherine comes face to face with Rascal Flatts ("Unshockable"), and Langston begins to investigate a series of murders committed by Dr. Jekyll ("Sin City Blue"), which may lead to his own brutal end ("Meat Jekyll").
