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.
Based on the hit movie of the same name, Uncle Buck is a fun-loving but irresponsible guy who needs a job and a place to stay. His brother and sister-in-law need some help around the house. And they just might be the answer to each other's problems.
