Joe Smith, an ordinary lad who works at the town bakery, becomes engaged to wealthy Mary Coronelli, and her snobbish aunt takes her to Europe to break up the affair. Using his own hard-earned savings, Joe goes after her, and is unjustly accused of embezzlement when the bakery funds are discovered missing. Riley the cop, a lifelong flatfoot well-liked by all, goes in pursuit of Joe; while in Europe, Riley falls in love with a German flapper in a beer garden, only to discover that she is the sister of Krausmeyer, the adjoining beat cop and Riley's nemesis. Riley brings Joe back to the United States, and he is proven innocent. All ends well.
