Cass Wheeler, a hugely successful singer-songwriter since the 70s, whose sudden disappearance from the music world has been the subject of intense speculation among her fans, is in the studio, taking a journey back into her past. Her task is to choose sixteen songs from among the hundreds she has written, for a uniquely personal Greatest Hits record. In the course of this one day, each song Cass plays sets off a chain of memories, leading us deep into her past. Hotly anticipated!
