"The thoughtful husband" decides Wifey needs a vacation and sends her to a quiet hotel. Her hand baggage is placed in the wrong room by a "dime-novel crazed" bellboy, who also places another guest's baggage in her room. The similarity of the numbers "66" and "99" cause the error, and when Ethel, a newlywed, arrives and is escorted to her husband's room she is astonished to find woman's wearing apparel thrown about. Ethel decides to make trouble and therefore removes the lingerie and places it in room 99, where it is discovered by "the thoughtful husband," who has also arrived in response to Wifey's telegram. In the small hours of the morning "the cabaret rounder" returns to the hotel, and when he attempts to retire in Ethel's room a general mix-up ensues, which ends satisfactorily.
