 After working in the noisy horn factory, just the sound of one drives Oliver into a violent fit. Dr. Finlayson prescribes a long, restful sea voyage, so Stan and Oliver rent a boat and set sail, unaware that escaped killer Nick Grainger has stowed away onboard. To disable the crook, the boys prepare him a meal using string for spaghetti, sponges for meatballs and soap for cheese. But Grainger discovers their plan and decides to make them eat the stuff themselves.
