Harry Carter is 11 years old when he creates HONC, an app for geeky kids like him who struggle to talk to girls. As it fast becomes the next big thing in the social networking world, it gets snapped up by American billionaire Trent Zebriski for 10 million, turning the working-class Carter family, including Harry's dad Tony, mum Liz and sister Ellie, into overnight multi-millionaires. However, their new-found wealth proves tricky for the humble Carters to handle, especially when Trent installs his bumbling advisor Oliver Campbell-Legg into their lives to help them change with their sudden fame and fortune. Rifts spark in the family as bus driver Tony struggles to keep his wife, son and daughter grounded, while they go mansion shopping, hire helicopters, buy cars, hold huge house parties and, to Tony's horror, replace his much-loved old sofa. Weaving in first loves, problems at school, life lessons and a farcical challenge to Harry's HONC inventor status, Carters Get Rich is a comedy for all the family: a warm and witty look at a modern household battling to hold onto their rags in the face of corrupting riches.
