Inspired by the same-named Broadway musical, Rock Of Ages starts with sweet Sherrie (Julianne Hough), a Midwestern girl who hops on a bus to make her way to Hollywood seeking fame and fortune as a singer. Within minutes of arriving, she's mugged and then rescued by well-meaning Drew (Diego Boneta), who's currently a bartender at the Bourbon Room, a famed nightclub and music venue, but really wants to be a musician, too. The Bourbon's flailing under a wave of financial distress, its owner, Dennis (Alec Baldwin), and his sidekick (Russell Brand) at their wits' end. There's also the mayor's ultra-conservative wife (Catherine Zeta-Jones), who's gunning for the club. Enter Stacee Jaxx (Tom Cruise), star of mega-band Arsenal, who's launching a solo career. His manager (Paul Giamatti) has promised to hold Stacee's first show at the Bourbon. Can Sherrie resist the pull of Stacee, her rock god? Will she and Drew ever make it -- in love and in music?
