High Play (1917)

Wealthy banker John Sevier is engaged to Elaine Morier, who runs an upscale gambling club with her father Gerald. One night at the club John stops a fight between club employee Jim Hammond and a wealthy young customer named Tom Leonard. He takes Leonard home and meets his sister Marion. The next day he discovers that his banking partner, Jim Collins, has made too many bad investments with the bank's money and the institution is in danger of going under. John promises to use his own money to save the bank, but Elaine, outraged, breaks off their engagement. However, Marion and Tom congratulate him on his courage in putting up his own money to save the bank. Elaine and her father--who were scheming to take John for his money all along--realize that they made a mistake and try to get the two back together again. Complications ensue.
