(S05E01) I love this show and I'm thoroughly excited that it's back. I still think it's the best in the CSI franchise and after last year's cliffhanger, this is the one premiere that I've honestly been looking forward to. We pick up right where we left off, with Horatio and Delko in pursuit of Antonio Riaz, the drug kingpin responsible for the death of Horatio's wife (and Delko's sister) Marisol. Riaz has fled the country thanks to the deal he cut with the Feds. Next stop? Brazil.
