A man comes to earth, whose power stems from sunlight. In darkness he is incredibly weak, but in sunlight, he has powers & abilities that defy logic. This was such a great show when it aired, but like many other sci-fi adventures of it's time, it was left at the wayside. If this ever becomes available on tape or DVD, I'd snatch it right up. Judson Scott was a great young talent. A must see for 80's SF watchers.
