Artie Decker has been recently fired from his job as a
sports commentator for the
minor league Fresno Grizzlies, due to his old-fashioned personality and lack of
social media savvy. His daughter Alice calls, asking him and his wife, Diane, to come to
Atlanta to babysit her children, while she and her husband Phil attend an entrepreneur convention in
South Carolina. Artie and Diane are at odds with Phil and Alice's
helicopter parenting and learn of their grandchildren's various problems: the eldest daughter Harper is an
overachiever, the middle son Turner has
stutter, and the youngest son Barker has an
imaginary friend, Carl the Kangaroo. The grandparents attempt to bond with the children at a Chinese restaurant, only for Artie to accidentally upset Barker and ends the night in chaos. The next morning, Alice is unable to part with her children, so Phil goes in her stead and their boss gives her an assignment to redesign the website for the
X Games. Artie uses this to his advantage and arranges an interview for the role of sports commentator. In an attempt to win over his grandchildren, he breaks several of the rules Alice has set for them, letting them watch horror movies and eat sweets. Despite being upset, Alice agrees to join Phil to South Carolina after Diane tells her that she and Artie will never be good grandparents if they never get a chance. At Harper's violin practice, her tutor, Dr. Schveer, berates her, leading Diane to threaten Schveer. Artie allows Barker to skip a playdate in order to take him to the skate park where his interview is being held. However, Barker slips away from his supervision, nearly getting run over by
Tony Hawk while he is skateboarding, and the incident is broadcast on the news. He returns to learn Turner got into a fight with his bully at school, after Artie had tried to teach him a lesson about confidence, and shows him the
Shot Heard 'Round the World event during a discussion. Meanwhile, Phil and Alice witness the news broadcast of the skatepark incident and return home. The tension comes to a head when Alice discovers Diane has allowed Harper to attend a party the night before a violin recital and Barker claims Carl has been hit and killed by a car. Alice eventually reconciles with Artie and Diane, and, sensing that Harper has lost her passion for music, allows her to withdraw from the recital. Turner takes her place on stage and overcomes his stutter by reciting the commentary from Shot Heard 'Round the World. Afterward, Artie and Diane successfully reconnect with their grandchildren, and Artie takes up a new job as a commentator for an Atlanta
Little League Baseball team alongside Turner. ==Cast==
