Just a woman (1925)

Robert, a young steelworker, lives with his family and George, a good friend who has invented a new method of refining steel and promises Robert that they will split the proceeds if they sell the process to their employer. Robert goes to the company's board of directors and receives what he considers to be a good offer, but his wife June doesn't think it's enough. She talks to the board and persuades them to make George the company president. Now that he's rich, Robert becomes convinced that his wife is having an affair with George, and he embarks on his own affair with a sophisticated, attractive--and ambitious--woman.
