Join siblings Amicia and young Hugo, as they struggle through the heart of the brutal and ruthless world of 12th century France. The rats swarm in uninterrupted waves throughout the Kingdom of France. In the disease-devastated villages, countryside and battlefields, they devour everything in their path, men and animals alike, to satisfy the endless hunger of their ever-increasing numbers. The faint glow of the flame Amicia holds appears to be the only thing that repels this uncontrollable and voracious mass’s relentless advance…
