Highlander The Series - Season 1
I loved this show. I'm re-watching it right now on Hulu.com. If you don't know the story, Duncan McLeod is an immortal from the highlands of scotland. He's 400 years old and trying to live a semi normal life except for the fact that "there can be only one". An ongoing battle between all the immortals on the earth. In order to kill an immortal you have to cut off their head. Lightening flashes yadda yadda yoo and you absorb all their power and knowledge. Cool, right.
