The second "Highlander" movie, again with Christopher Lambert and Sir Sean Connery. It's the year 2024, and all of the ozone above Earth is gone. To protect people from dying, MacLeod helped in the construction of a giant "shield", several years ago. But, since there isn't anyone left who's Immortal after MacLeod's victory in the previous movie, he has stopped being an Immortal. Now he is just an old man, until one day some other Immortals arrive on our planet. You see, the Immortals come from another planet.
