Calling all Robert Duncan fans! Our trusty Castle composer will be lending his musical talents to another ABC show come fall, and it sounds like a nail-biter!

Last Resort follows the Colorado, a U.S. ballistic missile submarine that has just received orders to fire nuclear weapons at Pakistan. As the crew awaits confirmation, their ship is targeted, hit, and sinks to the bottom of the ocean. Now considered rogue enemies, Captain Marcus Chaplin and XO Sam Kendal (portrayed by Andre Braughe and Scott Speedman) must lead their passengers to safety.

As you may have guessed, these wayward refugees find themselves on an exotic island, where they set up camp to start a new life.

So basically, it's Lost meets The West Wing — but with way better music, obviously.

What say you, Castle experts? Is Last Resort worth a first look?
