Story details from some article.
The film will explore the You Seminar, an academy where souls learn how to build passion within themselves before graduating and inhabiting a newborn child. Foxx plays, Joe Gardner, a man with a deep love for jazz, who is stuck as a middle school music teacher. After years of longing to perform onstage rather than teach, Joe finally gets his big break after an open mic at the Half Note Club that impresses the other players so much that he gets a gig.
But as he celebrates, an accident separates Joe from his soul, and his soul travels back to the You Seminar, where he meets other souls-in-training that help him find his way back to Earth. Among them is 21, played by Fey, a soul who has spent eons at the You Seminar and has a dim view of human life.
