Lincoln is four years old. He likes going on adventures with his mum and creating worlds in his imagination. Today he's playing in the sand pit at the zoo, with his favourite toy heroes and villains. Joan is constantly amazed by Lincoln. Each day he changes: learns, grows. Motherhood has surprised her with its fire, its animalistic fervour. She'd do anything for him; she'd die for him in a heartbeat. Robby has had enough. He's ready to change the world. Robby's gone to the zoo today, too. He´s about to become the villain of Lincoln's imagination, and Joan will need to summon everything she has to become her son's hero.
