Interestingly, a friend lent me a DVD player and that led me to the opportune (if illegal) purchase of a dee-bee-dee copy of the show's Season One. My God, Heroes overload and loved every minute of it!
The plot is fairly simple: individuals across the globe woke up one day and realized that they can do extraordinary skills, such as fly, teleport, regenerate, paint the future, etc... You name it. They go about discovering their powers and then ultimately learning their mission to save the world from a nuclear explosion.
And yes, Gilmore Girl's Jess (Milo Ventimiglia) is in it. Ahloveeet!
