She was a girl from Boston with a voice from heaven, who shot through the stars from gospel choir to dance floor diva. But what the world didn't know was how Donna Summer risked it all to break through every barrier, becoming the icon of an era and the inspiration for every music diva who followed. From Janet Jackson to Beyoncé, they all began with Donna. Three actresses play the role of musical icon Donna Summer at different points in her life as "Diva Donna," "Disco Donna," and "Duckling Donna," while an inexhaustible ensemble of almost entirely women tear up the stage. Summer takes us through her tumultuous life and tempestuous loves, and includes a mega-watt dream list of musical hits, including "Bad Girls," "MacArthur Park," "She Works Hard for the Money," and "Last Dance."
