Broncho Billy tells Geraldine that she will be throwing her young life away by marrying such a degraded fellow. Seeing the look of disappointment on her face he finally consents, thinking that his sister might be able to reform Church. A year or so later Geraldine returns to Broncho Billy's home with her infant child, having been deserted. Broncho Billy, determined to find Church, discovers him hiding in a barn, a fugitive from justice. Church is taken to Broncho Billy's home, where at pistol point he is married to Broncho Billy's sister. The law then takes its course.
