Raph, Leo, Mikey, and Donnie are becoming the heroes they are destined to be. But nothing can prepare them for what they face on, and below, the streets of NYC, where they discover a hidden mystical world and wield brand-new, powered-up weapons. The Turtles face formidable foes, battle bizarre mutants, wrestle a heavyweight champ, and still make time for the best pizza in the city!

Celebrating family, friendship and faith, the story unfolds in Atlanta, Georgia, as Cyrus DeBarge and his best friend Kris McDuffy reunite with their childhood friend, teenage singing sensation Roxanne 'Roxie' Andrews whose music label is sponsoring a songwriting contest at a teen club. The movie includes 12 musical performances that showcase the songs and musical breadth of the soundtrack including hip-hop, rap, gospel, R & B and pop genres.
