Rosalinda is a Majestic, trapped on the enchanted Sinner's Isle, under the watchful eye of her mistress. She's the prized commodity at this year's Offering, a week-long fiesta for the wealthy to engage in drink, damsels, and debauchery. Rosalinda and her best friend Joanna concoct a plan of escape–only to get caught by their mistress, who takes Joanna hostage. Meanwhile, the handsome, swashbuckling Mariano is marooned after the king's fleet attacks his father's ship. Mariano is stranded on the isle with nothing but a chain spelled to guide him to his heart's desire. When Rosalinda nicks his prized possession, Mariano begrudgingly agrees to help the bewitching thief find her friend then secure them safe passage off the isle. As they try to outwit the other, their attraction for one another grows. But if they can't learn to trust each other, they may not escape Sinner's Isle before time runs out.
