Frankie's sister, Janet, comes to the rescue and offers to help run the Heck household while Frankie studies for her dental assisting school finals. But the sheer amount of disorganization in the house throws perfectionist Janet for a loop. Meanwhile, when Cassidy's ex-boyfriend pays an unexpected visit from college, Axl tries to take the high road and not act like a jealous boyfriend; and Sue wants to legally change her middle name -- which is also Sue -- in order to have a normal name on her driver's license.

After successfully graduating from dental assisting school, Frankie attempts to interview for a job but discovers that, when asked about herself, she doesn't quite know how to describe who she is. Meanwhile, when Axl gets his band their first paying gig at the Orson Dollar Days, Sue becomes a 'Yoko' to boyfriend Darrin's 'John' and begins to offer unwanted advice to the group; and when Brick informs Frankie and Mike that he has joined the Prairie Scouts, Mike ends up reluctantly having to lead his quirky troop's camping trip. Jack McBrayer guest stars as Dr. Goodwin, who interviews Frankie for a possible job.
