Highlander: The Series - Season 3 Episode 5 Rite of Passage

Michelle Webster, the rebellious teenage daughter of a friend of MacLeod's, drives away from her parents' house in a rage and right over a cliff. Trauma surgeon Anne Lindsey tries her best to save Michelle, but it's too late. MacLeod rushes to the hospital to comfort his grieving friends -- and sneak their newly Immortal daughter out of the morgue. He tries to train her in the arts of Immortality, but Michelle just wants to have fun. She meets Immortal Axel Whittaker who promises her all the fun and adventure she could imagine if she stays with him. In flashback, we see that Axel uses beautiful new Immortal women as bait to trap other Immortals and take their heads -- MacLeod barely escaped with his in 1896 Boston. Axel uses Michelle to lure MacLeod to his yacht, where they continue the battle they started a hundred years before. MacLeod defeats Axel. Michelle, witnessing the fearsome power of the Quickening, agrees to be trained as an Immortal under the protection of Amanda.
