It's 1983 in Sunshine, Melbourne, and everyone at Marly's school is collecting Donkey Kong cards. Marly wants some cards too, but she has no money to buy them. Then she has a fantastic idea to start her own business! Marly's money-making venture brings her something she hadn't planned on: new friends in a part of Melbourne that she never knew existed. And of course she knows how to find her way home again. Or does she?.
