Harris Malden wears his insecurity on his face in a curious disguise for everyone to see. No one in the neighborhood, not ever his best friend Paul or his brother Melvin, has the heart to tell him how ridiculous he looks with the thick, black lie about his lip. Harris Malden fakes his facial hair, and as far as he’s concerned, nobody can tell. However, like dealing with a drunken uncle, it's easier to let him be than confront the problem. Harris has a sweet gig as a draftsman at a local firm, and everyone on his block likes him. Despite the big ol' fake mustache, everything is fine and dandy-- until Paul brings an outsider to Harris' twenty-fifth birthday party. No one knows what to do after she shouts, "YOU FAKE YOUR MUSTACHE!" The whole gang has to deal with the repercussions of Harris' breakdown.
