In the course of a trip Max purchases a horse to be given to his wife as a birthday present. Their birthdays are but a few days apart and upon his arrival home his wife presents him with a watch containing a miniature picture of herself. Max's son removes his wife's photo and replaces it with that of an actress. The wife discovers the change and there is war, vocal and physical. However, Max explains and is forgiven, until his wife opens a letter addressed to Max, which reads. "Got her off all right, but had trouble putting her on train. Does your wife suspect?" She does suspect. She does worse things than suspect. She reports Max to the police as a white-slaver. The police arrive and a bloodless battle ensues. Honors are about divided until the wife learns that the note refers to a mare. Then she turns upon the police and routs them.
