When Justin attempts to use magic to make his mentor Baxter Knight's weather predictions come true, he angers Mother Nature and winds up with his own personal rain cloud. Meanwhile, Alex partners up with Mr. Laritate as Deputy Russo and suddenly turns "good". Justin asks her for help, and the two are lectured by Mother Nature on the importance of helping the environment.
Meanwhile, Max chooses a cop who can also sing as his mentor, and inspires the cop to sing while he's on duty. However, the cop gets hit in the head with candied yam- piece of hail that Justin created, causing him to loose his singing voice.
Later, Alex's "goodness" comes short when Mr. Laritete punishes her with a month of detention for giving Harper the key to the teacher's bathroom. Alex thinks the punishment is unfair, but Mr. Laritate explains it is only part of his method of fitting the punishment to the student, rather than the crime they've committed. Mr. Laritate also tells Alex that she is the only student he will never give up on, flatteringly calling her an "evil genius".
In the end, Baxter Knight ends up losing his job, but Justin suddenly becomes unfazed when the new weather girl, Heather Nokatomi is announced.
