Highlander S06E05 - Patient Number 7

Police at her heels, killers on her trail, Kyra is on the run, with no memory of who -- or what -- she is. In the streets of Paris, she runs into Duncan MacLeod, who spins a wild story: that he and Kyra were lovers once, some three hundred years ago. That she is a soldier, a warrior. That she is Immortal. Kyra doesn't believe a word of it... but if it isn't true, then why is someone after her head?
