Dollar Dizzy (1930)

Charley and Thelma are millionaires, each trying to elude suitors who are trying to marry them for their money. Charlie gets word that a rich uncle has died, leaving him millions. Attorneys advise him to repair to a resort and avoid gold diggers. Once there, word spreads among the single women, and several try to ensnare him. At first he's gullible, then he cottons on, so when Thelma, a wealthy young woman, mistakes him for a fortune hunter, he dismisses her as well. A manager's error puts Charlie and Thelma in the same suite, and both think the other is prospecting. A dressing gown, radio, bare feet, pistol, keyhole, fountain pen, bedcovers, and a suspicious hotel detective join the mix-up. But wait, was the inheritance a mistake?
