Set in a somber, shadowy Venice, the film opens with the mysterious disappearance of Dr. Carlo Pavani, a well‑respected executive at Assicurazioni Generali. His absence causes much concern in his upper‑class household. Several days later, his body is found washed up onto the steps of a palazzo on the lagoon.

In Italy, Checco Dal Monte manages a troupe of traveling performers with plenty of heart but minimal talent. At a small town engagement, he encounters the starry-eyed, gorgeous Lily Antonelli, and hires her as a dancer on the show. Vivacious Lily quickly sells out crowds and earns the resentment of Checco's mistress, Melina Amour, but the fledgling performer has far bigger ambitions and soon sets her sights on a higher-profile role.
