The marriage of Rupert and Sarah is on the rocks, and their friends Charles and Madge, both of whom are lawyers, agree to handle the divorce. After the curtain has been up a few minutes, Rupert forgets his lines, has a brainstorm, and threatens to kill Charles in full view of the audience because he’s been having an affair offstage with Rupert’s real wife, Madge. The rest of the cast try to ignore the incident and forge ahead with the original play, but Rupert picks up a knife and advances on Charles, who is forced to take cover in a large cabin trunk, which is on the set at the time. A real-life marital comedy now evolves. The play is a light-hearted tilt at the complete theatricality of stage folk.
