Riley the Cop (1928)

Joe Smith, a young bakery worker, gets engaged to Mary Coronelli, who comes from a wealthy family. Her snooty aunt takes Mary to Europe, hoping to break up the couple, but Joe uses his savings to follow her there. Unfortunately, he is falsely accused of embezzling money for the trip from the bakery, and Officer Riley, a well-liked local cop, pursues Joe to Europe. While in Germany Riley falls for a young flapper in a beer garden, but he's in for a surprise when he finds out who she really is.
