The New Jersey family gets its new housekeeper Lisa via Australia. Danny tries to woo beautfiul Lisa into a romantic encounter in New York City. Lisa lays down the law of the house and says she will not submit to the advances of an employer. So Danny and his friend drill a hole in the bathroom wall to spy on her. Lisa discovers this and does not care for the attention.
The family adds a second car which will be time-shared by Danny and Lisa. The car helps Danny get a date with a high school babe with a reputation, Rhonda Graham. Unfortunately, Lisa is not forthcoming with the keys and the parents have the other car tied up in a romantic getaway. Sans car, Danny watches the leather and vinyl clad Rhonda walk out the door.
Danny thinks the target of his dad's romantic dinner is Lisa. Unfortunately for Danny, the dinner was supposed to be between dad and his mom. Comedy dealing with the misunderstanding ensues.
