Sibling rivalry gets the best of Will when Buck really hits it off with his architect office buddies. Rivalry of another kind spurs Alexis to drag her reluctant kids into a lip-sync battle hosted by the snooty president of her college sorority alumna.
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.
