Andrew, a wealthy Australian architect, takes life too seriously, whereas his PA Elizabeth is outgoing and fun-loving; a perfect foil for her somber boss. She is passionate about Celtic lore and language. With great reluctance Andrew answers a plea from his two elderly aunts to travel to Scotland before his uncle dies. He has no desire to visit the land his father left under a cloud many years ago, but Liz persuades him to take her along.

In the draughty and dilapidated castle, while exploring a disused attic, the pair set off a course of events that propel them back in time to 1050 where they meet Travis, coincidentally Andrew's double.
