Within hours of best-selling children’s author Julian Hartswood being cancelled for reposting a white supremacist, he discovers he has a neurodivergent son called “Austin”.

Austin invites Julian and Ingrid home to have lunch with his “embarrassing” family, while Ingrid contemplates some extramarital wham wham.

On a bonding tour with Austin, Julian covertly starts making a documentary film about “father and neurodivergent son quality time” in order to spring-clean his image.

Julian’s documentary capturing his growing relationship with Austin is now out in the open and Julian engages an award-winning filmmaker to finish the job.

Austin organizes a bespoke celebrity bus tour. Ingrid decides to expand her career to become an “‘illust-author” combining her illustrating career with writing, excluding Julian for the first time.

When Julian gets fired from his publisher and told his remaining books are to be pulped, Austin leads the charge to break into the warehouse to rescue whatever books are left.
