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.
ANYTHING ONCE! is a Cinderella story. Mabel works in a tailor shop, pressing clothes and dreaming of a better life. We're told that she's taken a lot of bumps in life and doesn't know where the next bump is coming from, which sounds uncomfortably close to the leading lady's real-life situation. Her boss is Jimmy Finlayson, but instead of playing the expected sourpuss Finn is quite benign here, and doesn't even punish Mabel when she accidentally sets his toupee on fire.
