Clan MacLeod is special; they protect all paranormal people in a world where "different" can be a death sentence. In return, they know who their soul mate is. Holly is on holidays in Scotland, and for Valentine's Day, she is attending a sixteenth-century period weekend party at the MacLeod castle. When she arrives she is surrounded by lightning that takes her back in time to the fifteen hundreds. There, she meets Laird Duncan MacLeod, who tells her she is his and she will marry him the next day.
