Lisa nags her soon-to-be ex-husband; she nags her son about finding a job. To deal with all her frustrations, Lisa turns to shopping. But when an inflated credit card bill comes due, she agrees to take a bribe from her son’s artistic friend, in order to let him paint a mural on her wall. To Lisa’s dismay, the mural turns out to be a life size portrait of a nude woman.

Unable to convince her son’s friend to paint anything else, Lisa agrees to leave the mural be. She loses her job, and finds work again at Lloyd’s Burger Barn. Depressed and neurotic, Lisa tries to host an art showing at her house, but after invitations went out with a somewhat less artistic painting (a zombie rabbit), no one shows up.

Lisa’s husband comes home to pick up the divorce papers, but is impressed with the new artwork. Thinking Lisa has changed her nagging tune, he invites her for dinner. Still in love with him, Lisa accepts, and harbors wishes of an amorous reunion. Later that night, they make up and everything seems to fall into place.

As the newly reunited family gathers around the television, a beautiful young woman interrupts, claiming to have been given an STD. Lisa is furious, and kicks her husband out. She discovers that her son's friend is secretly in love with her, and that the life sized nude on her wall is actually a portrait of herself. Disgusted, she nevertheless agrees to tell her husband that she has had an afair with the young man, to get even with him for a perceived liason. The beautiful young woman is revealed to be the son's girlfriend, and Lisa and her husband forgive each other.

In the end, they destroy the mural, but what they can't cover up is the fact that they never would have been reuinted were it not for the painting on the wall.
