Plot Catherine and Nick adjust to life working under D.B. Russell, following their demotions, while Morgan Brody joins the CSI team ("73 Seconds"), in the twelfth season of CSI. This season, the team investigate crimes including the murder of a family ("Tell Tale Hearts"), a drowning in chocolate ("Bittersweet"), a death at a mob museum ("Maid Men"), a cold-case killing ("Crime After Crime"), the zippering of a body ("Zippered") and a sadistic slaying ("Freaks and Geeks"). Meanwhile, D.B. struggles to keep control of his family ("Brain Doe"), Morgan's helicopter is hijacked mid-flight ("CSI Down"), Doc Robbins' wife finds herself at the center of an investigation ("Genetic Disorder"), and Catherine works alongside the FBI ("Ms. Willows Regrets"), before making a life-changing decision ("Willows in the Wind"). Then, it's all change at the LVPD when Russell recruits Julie Finlay ("Seeing Red"), fresh out of anger management and ready to tackle cases such as the theft of a house ("Stealing Home"), a crippling blackout ("CSI Unplugged"), a murder at an Alice-in-Wonderland style wedding ("Malice in Wonderland"), and a race-truck explosion ("Dune and Gloom"). Later, the troubles continue for the CSI's personal lives, as Finn and D.B. struggle to come to terms with their past relationship, Ecklie is gunned down, Nick leaves CSI, and the Crime Lab is placed under the supervision of an outside agency ("Homecoming").
