Max gets married, all right, but mother-in-law sticks around. She even follows her daughter, from whom she has never been separated for any length of time, to the railway station, and so anxious is Max to be rid of her that the happy couple forget to change the wedding clothes for traveling garb. Fond mother kisses her daughter good-bye with such fervor that Max, who is in the car already, goes off all by his lonesome when the train starts suddenly. He gets out at the next station, however, and "hoofs it" back. The honeymoon calls for a trip to Chamounix for a round of winter sports and good fun, but Max is forced to invite Ma to go along, too. Skating is the schedule for the first day of their stay, and big, fat mother-in-law also dons the glistening blades. Of course she falls all over herself on the ice and poor Max must cater to her and help her along. He tires of this, however, and she is left to crawl off the ice on all-fours. Sledding down the side of the mountains is next tried out, and Ma insists upon getting on behind Max, much to his disgust. She topples off half way down, however, and makes the rest of the descent without the formality of using a sled. They then take to the skis, and the much-despised persists in hanging on even in this dangerous pastime. She makes a flying trip down the slope successfully and Max, tired out because of her presence, suggests that they start back to the hotel. Mother-in-law is too big to get on the train, however, and is "boosted" on a mule tied behind the flyer. The rope breaks and the beast makes for its barn where Max finds her hanging to the top of the door and rescues her.
