What if your grandmother kept a secret that nobody knows? The Grandson is going to spend yet another summer at his grandmother's house. Between hose wars, soap bubbles and nights spent counting stars, there is a mystery he can't get out of his head: an old wardrobe full of boxes that his grandmother never lets anyone open. What could be inside? As he tries to discover the secret, the grandson realizes that some things do not disappear with time. They remain in the memories, in the stories and in the heart of those we love. The Grandmother's Secret is a tender and fun journey through childhood, memories and the love that unites grandparents and grandchildren. A show to see with the family, to laugh, to be moved and, perhaps, to leave the theatre wanting to hug someone. And you? Would you open the box of secrets? Ages 6 and up. Technical sheet: Based on the book The Grandmother's Secret. João Borges de Oliveira, creation.
