Immortals, men and women from all over the world who live hundreds, even thousands of years. Throughout the centuries they have walked among mortals in secret, moving and taking new identities as needed to stay hidden. Some abuse their power, treating normal humans as their playthings and carving a path of destruction to satisfy their selfish greed. Others use their gift to act as heroes, and protect humanity from evil.

But one thing holds true for all immortals. They fight a secret war amongst themselves, each with the goal of being the last. When a challenge is called forth two immortals meet blades and fight to the death. The victor takes his foes head and with it their power. There is only one rule in these battles, an immortal cannot kill on holy ground.

One of them is Duncan Macleod, a warrior born in 1592 in the Scottish Highlands. He has spent 400 years fighting evil immortals and protecting us in secret. Tonight with the drop of a head a great evil sets her sites on him, and lures him into her world.
