Brothers-in-law as business partners in a cloak and suit establishment with a ravishing model as go-between start off "Wild Papa" with much hilarity. The married member of the firm scoffs at his partner's declaration that the beautiful model vamp is in love with him. He proves otherwise when she enters the room. But she entwines her arms about his neck just as his wife appears on the scene. In the courtroom during the breach of promise suit, the plaintiff's version of the story is introduced. It shows her as an unsophisticated maiden romping about in the land of cows and grass. The defendant takes the stand and is about to tell the true story when he is instructed to read the defense concocted by his lawyer. In this he is pictured as the possessor of a lap dog and roller skates. The attorney releases a swarm of bees and the defendant is acquitted on the grounds of being "bughouse."
