Harry is a traveling hat salesman out west and he is mistaken for the Fighting Parson, who has been going around, punching out bandits and running revival meetings. So when he shows up in town and proceeds to charm the sinners by singing 'Frankie and Johnny' instead of 'Rock of Ages' he must fight Leo Wills for control of the town.
For some reason, Harry's Roach shorts are given short shrift in film history, just another rock on his career's pratfall. But looking at the actual work, I see an absolutely delightful short as Harry moves his naif into the sound era and begins to alter him for the new venue. A veteran of the stage, he sings, he plays the piano and he performs a fine eccentric dance. Nor are the solid comedy technicians at Roach averse to helping him come up with one of his better surrealistic gags for the final big fight scene.
For some reason, Thelma Todd appears only in a few crowd shots. This looks like it was cut down from three reels, or perhaps they simply built up the comedy boxing match and had to cut out her part.
