Margaret has given up her stage career to marry inventor Jerry Benson. Jerry fails to impress oil executive William Graves with his idea, but Margaret has better luck when she catches Graves' attention and she both makes the sale and becomes the object of Graves' obsession. Profits from the invention make the Bensons wealthy; however Graves schemes to steal Margaret from Jerry by swindling them out of their money and getting Broadway floozy Gloria to break up their marriage.
