The "Carry On" gang take on employment agencies in this labored edition to the long-running comedy series. Sidney James is Bert Handy, who starts an employment agency by the name of "Helping Hands, Ltd." Bert proceeds to hire a bunch of loonies to do a collection of screwball jobs employers want done. As is usually the case, the employees make hash out of every assignment given to them. In fact, the agency is so unsuccessful that their landlord (Stanley Unwin) tries to have the business removed from his premises by raising their rent. But the landlord makes a deal with Bert that if his company can fix up an old house, they can have a 99-year lease on the property. Chaos ensues.
