Charles is in charge of the Pembroke children when their parents are off on a week's vacation in Jamaica, their first one without the kids. Grandma Irene also arrives to help take care of things. She brings with her a very innovative sample of merchandise, a new kind of pizza, which she plans to launch with Charles' assistance. The offer she makes him is very tempting and Charles almost accepts it but backs out in the end, realizing that he does not need a new job. He has one already that brings him enough money to go to school, which is really all he wants. Grandma Irene decides that it would give her more privacy if she moved into an apartment close by and that she also is more than capable to handle her new pizza-selling campaign by herself.
