Lucy and Viv don't have enough money for their boys to stay at camp the additional two weeks. On the trip to pick them up, the car runs out of gas. The ladies have no luck at flagging down a passing motorist, but Mooney does. He catches the eye of a flirtatious little old lady who calls him "Big Boy." Learning the camp cooks have quit, Lucy volunteers herself and Viv to take over as chefs despite knowing nothing about feeding 200 people. In short order, the kitchen and most of the food is destroyed.
