Son-in-law Steve eagerly offers to do the housekeeping, rashly declaring that if all women organised their work efficiently, it could be done in just a fraction of the usual time. A belief which is hardly borne out by his own demonstrations.

With Bub permanently away in Ireland, Steve finally resorts to domestic assistance and the Douglas home is afflicted with a fiery dragon of a housekeeper named Fedocia. When Steve is desperately trying to solve the problem of getting rid of her the situation is saved by the arrival of Bub's younger brother Charley, a recently retired Ship's cook on leave.
