The kingdom of Liones is thrown into turmoil when the king's Holy Knights are corrupted by a distinctly unholy demonic power. The land's only hope is a band of powerful warriors known as The Seven Deadly Sins - an exiled group of oddballs who seem to spend as much time fighting each other as they do fighting their enemies. Princess Elizabeth desperately seeks their aid, but the leader of her would-be saviors turns out to be an undersized pervert with a broken blade and a talking pig! They are soon joined by a jealous giant, a fussy fairy, and an immortal bandit pining over his lost love. Can these people really be the legendary heroes she's looking for?
