Follows the adventures of Duncan MacLeod, an Immortal warrior, who in the present day owns and operates an antique store with his lover and soul-mate Tessa Noel, the only mortal to know his secret.

This season started by going back to the Highlands of Scotland when Duncan was only 13 years old; we got to see him in close contact with his cousin Robert. Ritchie, now an immortal with no false belief that Duncan will protect him and watch out for him, is ready to take care of himself. Hugh Fitzcairn, Amanda, and Methos make appearances.
