 A couple of tramps, down on their luck and hungry, decide to fake an exhibition boxing match for a promoter. Meanwhile, Pug, a good-hearted but boisterous fellow, takes on a gang of mashers who make unwanted advances to his girlfriend. Impressed by his abilities, the mashers decide to pass Pug off as Cyclone Flynn, the champion, and enter him in the boxing match. But the real Cyclone shows up, and he and Pug battle it out in the ring. Soon the fight progresses to include pistols, rooftop chases, and the Keystone Kops in hot pursuit.
