The employees at “Drake” mansion (Leon Errol), possibly suspecting trouble, hadn't received their salaries in seven months—their employer was broke. Undeterred, his resourceful valet, "O’Brien" (Jack Haley), devised a scheme to get them back on track. The plan involved staging a performance of George Bernard Shaw and presenting parlour maid “Millie” (Michèle Morgan) as the wealthy daughter of the house, with the hope of securing her marriage to a man of considerable fortune. Millie proved surprisingly adept at transforming herself, but the arrival of young butler Frank Sinatra (no character name needed!) quickly complicated matters. The story itself seems almost unimportant compared to the numerous pleasant McHugh and Adamson songs sprinkled throughout. Standouts include “I Couldn’t Sleep a Wink Last Night” and “Lovely Way to Spend an Evening,” and Sinatra isn't alone in showcasing his singing talent; Barbara Hale, Mel Tormé, and comedy pianist Victor Borge also get their chance to shine musically. As expected, the elaborate plot doesn’t pan out as intended, with genuine romance overshadowing any calculated schemes. The cast members work together quite enjoyably, blending intrigue with a dance and a handy dumbwaiter. It's an uplifting movie from wartime times that likely won’t leave a lasting impression, but it offers simple entertainment for ninety minutes.
