Set in the turbulent 1970s, this film explores the age-old questions of "Where do I come from?" and "Why am I here?" Centered on twins Jimmy and Pam Flinders, the musical begins with a group of spirits making promises to each other before coming to live on Earth. However, with those promises forgotten, Jimmy, Pam and all the others find themselves on very different paths once on Earth. Jimmy loses himself seeking stardom, and struggles with his faith, his identity, and his relationship with his family. Devastating tragedy strikes Pam, and her family. But will this devastation destroy Jimmy or help him rediscover who he really is? And what of the others? Will their promises be kept or be forever forgotten?
