Inspired by the movie of the same name follows the life of Duncan Macleod, a clansman of Connor Macleod, star of the movie. Duncan's an immortal, who has been alive for four hundred years. The first season follows his ...展开attempt to live a normal life with his French girlfriend, Tessa. He took in a young street kid named Richie, whom he confided his secret--that he's an immortal and can only be killed when he is beheaded. And also once beheaded their power goes into the one who beheads them, which means that there's always an immortal who wants to take their head. The second season Duncan discovered there's a secret society, whose duty is to record what immortals do. And the one assigned to "watch" Duncan is Joe Dawson. It seems that some of their members feel that immortals are abominations and must be disposed, which they tried. Also Tessa and Richie were killed but Richie then learned that he is an immortal which is why Duncan took him in and confided in him. Duncan would constantly run into Amanda who ia an immortal and a thief but Duncan tries to reform her and has occasional success. He would also meet Methos who is supposedly the oldest immortal. Now the first half of each season begins in North America while the second half takes place in Europe, mostly France.
