This season on CSI: Miami, the team faces one of its toughest cases yet: solving the case of who shot Horatio Caine. In addition, the CSIs must investigate crimes involving gasoline siphoning, taking on the Russian mob, the unexpected return of Horatio’s ex, Julia Winston (Elizabeth Berkley), and Delko and Calleigh’s lives being put in jeopardy while trying to protect a witness in danger. The show marks its 150th episode this November.
