Stephanie and Kimmy resort to snooping around Steve's apartment when they suspect that he's cheating on DJ with another girl. Meanwhile, Jesse, Joey, and Danny tape an infomercial to sell a hair care accessory that Jesse invented, which ends in chaos.

Jesse and Becky are concerned that Nicky and Alex won't socialize with other kids, and attend a parent support group. In the meantime, Stephanie and Michelle learn D.J. has received a traffic ticket and request full access to her wardrobe or they'll tell Danny.
