New Tuesday, December 23 8/7c. One Direction's first U.S. network special will offer a rare inside look at the wildly popular band through a combination of documentary material, comical stunts and musical performances. The special features exclusive behind-the-scenes footage from the South American leg of their 2014 "Where We Are Tour" and follows the band as they recorded their No. 1 album, "FOUR," on the road.

Viewers will also experience One Direction's music as they stage a special intimate concert for lucky fans at Universal Orlando Resort, where the band performs a selection of songs from "FOUR" as well as some of the biggest hits off their three previous albums. The hour-long telecast also finds the boys giving unsuspecting fans the shock of their lives by introducing themselves in disguise at the theme parks, as well as the bandmates interviewing each other aboard a high-speed roller coaster.
