Honeymoon Blues

On the night of Hugh's wedding to Betty Lou, Mr. Wright, boss of the detective agency Hugh works for, assigns him to recover some love letters that Fifi LaRue has been using to blackmail a wealthy oil-man client of the agency. Fifi lives in the same building as Hugh, so Hugh slips Betty Lou some sleeping pills and prepares to go after the letters. But there are some mix-ups involving a jealous boyfriend with a sword before Hugh obtains the letters, and returns to his bride.
