When the leading lady of a low-budget musical revue sprains her ankle, the assistant stage manager is forced to understudy and perform in her place, becoming a star and finding love in the process.

The assistant stage manager of a small-time theatrical company (Polly Browne) is forced to understudy for the leading lady (Rita) at a matinée performance at which an illustrious Hollywood director (Cecil B. DeThrill) is in the audience scouting for actors to be in his latest "all-talking, all-dancing, all-singing" extravaganza. Polly also happens to fall in love with the leading man (Tony) and imagines several fabulous fantasy sequences in which the director is free to exercise his capacity for over-the-top visuals in this charming 1920's era flick.—Bliss Blood <[email protected]>

It's the beginning of the talking movie era. At the Theatre Royal in Portsmouth, England, a second rate theater troupe run by "Mr. Max" Mandeville is in its run of a musical called "The Boy Friend". For their shows, there are usually more people performing on stage than there are in the audience. On this day, the lead actress, Rita Monroe, has just injured her ankle, leaving the assistant stage manager, a shy waif of a woman named Polly Browne to assume the lead female role just before her first scheduled entrance. The timing is bad as in the audience for this matinée is famed Hollywood movie director De Thrill, who is scouting for his new all talking movie musical. So there is much pressure on Polly not just to perform adequately, but to save the production to ensure it pleases De Thrill. While many of the actors end up playing solely to De Thrill - especially featured chorus members Maisie and Tommy, who try to one up the other on stage - Polly only wants not to embarrass herself, and have real life mirror the on-stage story as she is in love with the lead actor, Tony Brockhurst.—Huggo
