Immortal tyrant Kortan raids a village for slaves. Young Quentin MacLeod and his mother are killed in the attack but Quentin soon revives. Immortals Ramirez and Mangus help him and his kid stepsister Clyde find their captured clansmen.

Ramirez takes Quentin to meet Stevenson a once daring and powerful Jettator who built a dam before the Great Catastrophe that generates a special kind of energy called electricity. However, Stevenson is nowhere to be found as his mysterious ferryman continues to lead Quentin and Ramirez into a trap.

After encountering a burning water called oil, Ramirez and Quentin try to visit a Jettator named Errol who knows all the secrets of the Earth. They instead find a tortured and demented soul named Melvyn who thinks he is an Immortal. Making things worse Quentin's sister Clyde looks like Melvyn's daughter, whom he believed to have perished at the hands of Kortan's Hunters.

Kortan sends forth his Hunters lead by Arak to confront the Dundees. Living among the Dundees is Quentin, who has lived his life as a Dundee. After Arak kills Quentin the Quickening restores him to life and his dying mother tells him he is a MacLeod and is the chosen Immortal to defeat Kortan. Quentin promises his mother to rescue the Dundees and follow his destiny. Ramirez then appears after waiting seven centuries to reveal the oath taken by himself and other Immortal such as Mangus to become Jettators. Now is the time for Ramirez to take Quentin into being his apprentice. But can Ramirez teach the young boy enough before he confronts Kortan for the first time?

The Dundees are attacked by bandits with a terrible weapon used in a time before the Great Catastrophe. Ramirez learns it is a machine gun when he performs a magic called surgery upon a wounded Dundee. Quentin has gone with the Dundees in search of the bandits and the weapon. They find the bandits held up aboard the remains of an ancient aircraft carrier.

Quentin has a fear of heights and must conqueror that fear before he recieves the quickening of the winds.
