The story of Connor Macleod, immortal Scottishman. Begining with his humble childhood in 1536 where he is banished from his own village, and leading up to the dramatic climax in 1986.
Apparently, there can be only one immortal when everything is said and done, therefore they must seek each other out over the ages until only a handful remain, the only way they can die? Beheading.
And now they must gather in New York to discover who "The One" will be.
