Alex O'Loughlin fronts the Hawaii Five-0 reboot, taking over the Steve McGarrett role previously played by Jack Lord. McGarrett returns to the Aloha State to investigate his father's murder. The governor (Jean Smart) enlists him to form an elite task force, which includes Detective Danny "Danno" Williams (Scott Caan), Chin Ho Kelly (Daniel Dae Kim) and Chin's cousin, surfer-turned-cop Kona (Grace Park).

Jason Ritter, Laura Innes, and Blair Underwood lead the ensemble of NBC's twisty mystery thriller. A presidential assassination attempt, a missing person and a CIA cover-up are among the events that aren't the event in the head-scratching drama.

For Law & Order: Los Angeles, Dick Wolf takes his classic cops-and-lawyers approach to sunny California. Skeet Ulrich and Cory Stoll will police the mean streets while Alfred Molina and Terrence Howard hold down the courthouse.
