During the 16th century, a mercenary force known as the Sha'Mar brotherhood was established to protect and maintain order in the city of Jerusalem. Among them, a young mercenary named Irijah of Lifta became renowed for his skill and integrity as he proudly fights for Israel. In 1586 however, his life began to change during a mission where he encounters a trio of freedom fighters from Ireland, and now must join forces with them to prevent a full scale war that threatens the peace of his country.
