Misled by schoolmate Richmond Matzie, Punky shoplifts a winter scarf for Henry as a Christmas present, and unknowingly switches bags with Mike -- and an innocent Mike is put in jail, but Punky and Henry get Mike out when Punky explains everything.

Punky wants Henry to stand up for her rights when Richmond Matzie and his father and the boys won't let Punky race the new remote control car that she won, just because she's a girl. It turns out that Henry feels the same way the boys do, until Mike has an eye opening talk with Henry, convincing Henry to stand up for Punky against Mr. Matzie and Richmond, who reluctantly allow Punky to enter her car in a championship race that she wins.
