Jack and Blanny Wheeler live in the apartment above Laura and Billy Bartlett.

One night Jack goes to play poker and leaves Blanny with the Bartletts. Laura goes out with Philip. Blanny and Billy commiserate about their loneliness, and concoct a scheme to arouse their spouses' jealousies. They taste various liquors, become intoxicated, and fall asleep. Jack, Laura, and Philip return. Jack and Laura both threaten divorce until the explanations are made, and the couples are reunited.
