Bulldog Drummond is a British WWI veteran who longs for some excitement after he returns to the humdrum existence of civilian life. He gets what he's looking for when a girl requests his help in freeing her uncle from a nursing home. She believes the home is just a front and that her uncle is really being held captive while the culprits try to extort his fortune from him.
Charming Sinners was a stilted adaptation of Somerset Maugham's play The Constant Wife. Robert Miles (Clive Brook) starts the ball rolling when he falls in love with Anne-Marie Whitley (Mary Nolan), the best friend of his own wife Kathryn (Ruth Chatterton). In retaliation, Kathryn begins a flirtation with her former boyfriend Karl Kraley (William Powell). After reels and reels of verbal fencing, the status quo is re-established, and Robert and Kathryn are reunited.
