為了尋夢，來自愛荷華州的鄉下姑娘Ali (Christina Aguilera 飾)來到洛城打拼，並在Tess (Cher 飾)經營不善的舞孃俱樂部打工。初期雖然只是當個女侍，但Ali 始終憧憬著有天能站上舞台演出。

With the help of a sharp-witted stage manager (Stanley Tucci) and gender-bending host (Alan Cumming), Ali makes her way from the bar to the stage. Her spectacular voice restores The Burlesque Lounge to its former glory, though not before a charismatic entrepreneur (Eric Dane) arrives with an enticing proposal…
