When Harley's siblings refuse to try out her latest invention called the Grocer-Whee, she turns to Ellie to give it a test run, but Ellie worries she will get hurt. Knowing how sheltered Ellie's life has become because of her mother, Harley works on being a good influence to her best friend by helping her through her fears.
Eventually, the two ride the Grocer-Whee but end up taking out the Peters' mailbox. Thinking Ellie's punishment will be no big deal, Harley later feels guilty after Ellie tells her that she is being sent to boarding school by her mother. With Daphne, Lewie and Beast's help, the two girls concoct a plan to convince Ms. Peters to change her mind, but she sees through their act. Still, Ms. Peters is made aware of her daughter's feelings about boarding school and cancels her enrollment. Harley is relieved, but after doing research on the school, she realizes Ellie should not pass up the opportunity and has to convince her to go, even though she will miss her.
Meanwhile, Rachel joins Ethan's film club at Tom's bait shop, but Suzy and Tom do some investigating after seeing what actually goes on there.
