Frank Rodie emerges as a very successful divorce lawyer, embittered after his own wife tricks him into innocently appearing as a co-respondent in a case and then divorcing him so she could marry a wealthy stockbroker.

He manages to get even by trapping his wife into a compromising situation after her husband sues for divorce.

Finally, Frank is called in to save his daughter's reputation when she is dragged into a divorce case, eventually winning her appreciation.
