In Hollywood, canine superstar Rexxx is literally top dog and gets top billing in some of the biggest movie blockbusters. But when Rexxx gets lost and ends up far from the red-carpet world of Tinseltown, he's completely out of his element. In the end, it takes a lonely boy (Josh Hutcherson) and a company of firefighters to give him a true sense of belonging. Todd Holland directs this family-friendly story.
