Dr. Burton's divorce is about to be effective when his flappery ex-wife Irene pays him a visit turning everything upside down. To avoid explanations to his bride-to-be and her mother they all take the train, including Irene and her lawyer, who will try to prevent him from committing bigamy, as the divorce won't be effective until midnight.
