Thirteen year old brothers Tim and Tristin are on a trip to an old greek town of Thessaloniki. The boys have had obsessions with the weapons of ancient times and have studied some of the skills involved with using them. Tim and Tristin have also experienced times in which they have done things that shouldn't be humanly possible. While in Thessaloniki Tim and Tristin meet sisters Aella and Fotia who also seem to have these powers as well. Aella and Fotia say that they are being chased and that Tim and Tristin should come with them.
