Burning Up Broadway (1928)

Harry Wells, a New Yorker, takes his friend Bob Travers, a westerner visiting the city, to a cafe for an evening of pleasure. When Bob becomes interested in Floss, the chief chorus girl, he incurs the wrath of Spike, owner of the cafe, who is in love with her. The next night Bob goes again to the cafe, where to their mutual chagrin he meets Harry. Spike, it is revealed, is a bootlegger in partnership with Nick, co-owner of the cafe. They find Bob snooping around, knock him out, and, taking Floss, whom they suspect of knowing too much, go off to run a big shipment of liquor. Harry, with a gang of roughnecks in his car, rescues Bob and trails Spike. When the liquor is being unloaded, Harry's men--all revenue agents disguised as hijackers--start a fight, and Bob rescues Floss. It is revealed that Harry and Floss are detectives pursuing Spike and his gang, and Bob and Floss find happiness in each other.
