Shirou Emiya is an average student that is dragged into a war over the Holy Grail, an item that can fulfill any wish or desire. The contestants all use spirit servants to fight each other, however as Emiya is a newcomer and unskilled he must join together with Rin Tohsaka to survive the battles. This is only a temporary solution, as Tohsaka's spirit servant Archer greatly dislikes Emiya for an unknown reason. (thetvdb.com)
