Laurel and Hardy, rat trap salesmen who are unable to do business in Switzerland, having no money to pay for lunch end up working for the hotel where a composer, who has run away from his wife, has taken refuge.

Stanley and Oliver are mousetrap salesmen hoping to strike it rich in Switzerland, but get swindled out of all their money by a cheesemaker. While working off their hotel debt, Oliver falls in love with a chambermaid, Anna, who in reality is a famous opera singer spying on her composer husband, Victor, while he works on his new opera. The boys are assigned to move Victor's piano to a secluded tree house, but become trapped on a rickety rope bridge high above an Alpine gorge when they're met halfway across by a gorilla.—Paul Penna <[email protected]>
