The Greatest Song: The Greatest Song is the coming together story of a successful music producer (Lamman Rucker - Tyler Perry's Meet the Browns) who thinks he's got all the answers, but heaven help him when he meets a pretty church choir director (Aida Rodriguez). Sparks fly as the pair tries to save two imperiled churches of different ethnicities. Their only hope... helping the choirs join together to win first prize in a National Gospel Competition. In order to reach their goal, the choirs have to overcome racial tensions and learn how to work together if they're going to have a prayer of winning.
