Bill, the henpecked husband, arrives at the hotel with Gale, carrying her dog and a grip. There is a sign which says, "No Dogs Allowed," so he hides the pup in the grip. The hotel clerk has been warned to look out for an anarchist, and when Bill acts queerly about his grip, the clerk demands that he open it. Bill refuses. The Anarchist appears, and his grip gets changed with Bill's. Then Heinie and Lillian arrive, and Bill again changes his grip for Lillian's. The clerk sends for the police, who open Bill's grip and find lady's lingerie. Bill has the grip with the lingerie, the anarchist the grip with the dog and Lillian and Heinie the one with the bomb. Gale takes Bill's clothes to have them pressed, leaving him in his underwear. He finds that he has his wrong grip and goes out to hunt for the one with the dog. Gale comes back, and the anarchist starts hunting for his bomb. He has opened the grip with the dog and been scared by it. Everyone gets into the wrong room, and keeps finding the wrong grip. At last the dog gets the bomb in his mouth, and they all chase him with it through the hotel. The bomb finally explodes and blows up the anarchist with it.
