After the pediatrician tells Mia and Casey that their newly adopted cat should not be around the baby, the news triggers a competition between Mia's parents and Maddie and Ben, who believe whoever takes in the feline will also be named the baby's guardian.

Casey heads out for a job interview and borrows a leather jacket without telling anyone, unaware that the coat has a history of bringing bad luck to its wearer. Each family member recalls a calamitous experience while sporting the coat. Among the tales of woe: Ben once accidentally interfered with the New York Yankee's Nick Swisher as the outfielder was trying to snag a fly ball.
