Starting today, CBS is making the premiere episode of Limitless available for free through its All Access platform.

Based on the Bradley Cooper movie of the same name (and the book that that was based on), Limitless stars Jake McDorman as a man who discovers a drug that allows him to unlock 100 percent of his brain's capacity. The series doesn't premiere until Sept. 22, but you can watch the first episode here.
