The docu-concert goes behind the scenes of Lopez's first world tour, which visits 65 cities and five continents, travelling 100,000 miles and reaching one million fans, producing 11,250 minutes of music, and requiring 500,000 sequins and 162 wardrobe changes. DANCE AGAIN combines riveting musical performances with a raw and candid look at Lopez's personal and professional life over a defining six-month period, when she challenges herself to go on her first world tour with her two young children in tow.
