Dapper song-and-dance man Jack Buchanan was both star and director of That's a Good Girl. Hoping to replenish his bank account, Jack Barrows (Buchanan) tries to marry his female cousin off to a wealthy American. This plan is sidetracked when Barrows, wandering backstage at the Milan opera house, is mistaken for a chorus singer and forced onstage, starting an altogether new plot tangent. None of this nonsense dissuades lady detective Joy Dean (Elsie Randolph) from tracking down Barrows on behalf of his creditors. That's a Good Girl is the film version of a popular stage musical which also teamed Jack Buchanan with Elsie Randolph.
