Alexis insists on riding along with Buck on his first day as nanny. But as Buck deals with a cranky school principal, searches for gluten-free cupcakes and stages a small break-in to obtain special food for the family's allergic dog, he drives Alexis to the brink. Back home Will tries to prove that he's capable of taking care of Miles, who is home sick from school.

Alexis is convinced that Buck is to blame for Miles' new, impulsive attitude after she catches him attempting a risky stunt for his YouTube channel. With Miles' punishment looming, Buck decides to throw a "going to jail" party while Mom and Dad are out, but unfortunately a creepy neighbor calls the cops and ruins their celebration. Buck, Miles, Tia and Maizy seek revenge and end up in a prank war.
