Magnificent Rogue is the title of a less than magnificent Republic programmer. Warren Douglas plays the title role, a wheeler-dealer businessman with fingers in several dirty pies. When Douglas is drafted, his wife Lynne Roberts is compelled to take over his business. Completely unaware of his shady corporate practices, Roberts suddenly finds herself commiserating with raffish characters straight out of Damon Runyon. How she comes out on top and reforms her husband forms the denouement of this lightweight comedy/drama.
