Feeling he has outgrown his old electric train set, Beaver (Jerry Mathers) is amenable when June (Barbara Billingsley) arranges to give the trains to a younger neighbor named Jimmy. But while he's cleaning and fixing up the trains, Beaver is overcome by a wave of nostalgia and has second thoughts about giving them up. As it turns out, Beaver's mind undergoes quite a few changes in the episode -- especially when he meets Jimmy's cute older sister Georgia (Toby Michaels).
