This lavishly staged and costumed fantasy is about young Jack (Tom Cruise) and his lady love Princess Lili (Mia Sara), and how Jack battles Darkness (Tim Curry) to save both the Princess and the world. When the peasant Jack takes Princess Lili to see the unicorns, the strongest animals around, he does not know that Darkness, with his cloven hooves, yellow eyes, and red skin plans on using Lili as bait to weaken the unicorns which he does -- and plunge the world into an ice age. Soon after that disaster, Darkness captures Lili and, Jack has to rally his elves and elvettes to rescue her and subdue Darkness at the same time.
