Love leads a man to his most evil deeds and forces him to change his ways in this Western. After being handed a dishonorable discharge during the Civil War, Mike McComb (Errol Flynn) becomes a professional gambler and follows a path of ruthless action to get what he wants. After moving out West and making a killing prospecting silver, McComb becomes a wealthy and powerful man, and he finds himself infatuated with beautiful Georgia Moore (Ann Sheridan). However, Georgia is married to Stanley Moore (Bruce Bennett), who works for McComb, so he arranges for Stanley to be given a dangerous assignment; Stanley is killed, and McComb sweeps the widowed Georgia off her feet. Georgia weds McComb, but in time she finds out the ugly truth about her second husband, leaving him behind. Devastated, McComb sets out to mend his ways and win Georgia back by serving more noble purposes. Silver River was the seventh Flynn vehicle directed by Raoul Walsh; it would also mark the last time they worked together.
