When Nick and his brother, Jimmy, are called in to work unexpectedly, Nick is forced to take the younger boys, T. J. and Kyle, with him to the fire station, which leaves Sam, Jack and Chris home alone. The boys recently found out that people give firemen in uniform free stuff as a way of showing their gratitude. When they combine this knowledge with the fact that Jimmy just dropped off a bunch of Nick's freshly cleaned uniforms from the dry cleaners, they put two and two together, which equals a heap of trouble.

It's Halloween, and the Savage boys are trying to figure out what to do for their annual prank. Kyle feels he's too old for trick or treating this year, leaving Nick and T.J. to go it alone. When Chris is forced to dissect a frog in class, he gets the idea – via a spooky visit from the ghost of the late class frog – of just what to do for their prank this year.

Sam's love, Angela, has a new boyfriend, and so Jack, noticing how depressed Sam is, encourages him to go to the mall with him to meet someone else. Sam reluctantly agrees, and when Jack introduces him to a very good looking girl, Erin, Sam can hardly believe it when she agrees to go out with him. It becomes apparent very quickly, however, that Erin's main priority is talking on her cell phone instead of actually talking to him. Meanwhile, Chris has taken a job selling glider planes from a cart in the mall.

Eager to earn money to buy Christmas gifts for their girlfriends, the three older boys find jobs at a lingerie store, but their jobs turn out to be less than glamorous and tensions arise when Sam gets promoted and Chris and Jack are left to do the grunt work. Meanwhile the two younger boys, Evan and T.J., are less than thrilled when Nick puts them to work helping with the fire station's annual toy drive for needy kids.

The boys administer their own form of CPR – complete with bicycle pump and toilet plunger – on Old Lady Riley when she has a heart attack on their doorstep, and are then wrongfully lauded as heroes. But when they're awarded the "Caring Kid Award," it's just too much to take for one onlooker who happens to know the truth.
