Zoolander 2 follows the antics of Derek and Hansel after their modeling retirement . . . which doesn't turn out to be much of a retirement at all. Thanks to a last-minute invite to Rome, the two re-embark on modeling in hopes of helping Derek regain custody of his son Derek Jr. What they find is instead Mugatu back at his usual game, trying to secure the Fountain of Youth by eating the heart of Derek's son. Luckily, both Ben Stiller and Owen Wilson find the time to strip off their shirts and bare their model bods!
