It is a time of crisis for the delightfully ghoulish family created by cartoonist Charles Addams. Gomez and Morticia's daughter Wednesday is growing up. Now eighteen, she has fallen in love with a "normal" boy, and to make matters worse, has invited him and his parents over for dinner. In one fateful, hilarious night, secrets are disclosed, relationships are tested, and the Addams family must confront the one horrible thing they've managed to avoid for generations -- change.
