Punky and Cherie sell cosmetics door to door for Lady Contempo Cosmetics, until they discover that Lady Contempo Cosmetics is a scam run by a con artist named Sidney. Henry washes his hair with Lady Contempo shampoo and wakes up the next morning with no hair on his head. Punky and the gang have to deal with angry customers who have also felt the various side effects of Lady Contempo products, and when they go to Lady Contempo to confront Sidney, they see that Sidney has cleared out, and it turns out that the reason why Henry is bald headed is because he washed his hair with Contempo furniture stripper that Sidney had disguised as Lady Contempo shampoo, and the reason why the blue face mask won't come off of Betty's face is because the face mask is actually kitchen floor wax that was disguised as the face mask cream. While they are in Sidney's office, A detective named Denko shows up looking for Sidney, who has cleared out.
