When soldier Robin happens upon the dying Robert of Loxley, he promises to return the man's sword to his family in Nottingham. There, he assumes Robert's identity; romances his widow, Marion; and draws the ire of the town's sheriff and King John's henchman, Godfrey.

Brother and sister Alfie and Elise keep wishing for more, until the night before Christmas when the strange and mysterious Wish Collector appears and whisks them off to the Land of Sometimes, where all their wishes can come true.
