Don't Give Up (1930)

Buster West breezes into town, offends a couple of girls, and shows up at the DA's office -- the District Attorney is played by his father, John West -- hoping to be an investigator. He is assigned to trail a gangster's moll, but naturally mistakes Carol Wines, the DA's daughter for her. Some vigorous and funny situations ensue, amidst the not-so-funny snappy patter.
