Little Vasiliki, in her dreams, discovers the... echo, which unfolds and grows, revealing to her another world! She wonders who could hear her own echo... Proudly and hopefully gazing at the majestic Epidaurus as the sun bathes her, she gazes at a landscape that looks like a scene from an ancient era. With the power of her voice, she discovers her own sound world, the world with echo. Her dream comes true. However, somewhere along the way, she jumps to the house of the ancient god of healing, Asclepius, at the Asclepius. Her exclamations flood the entire ancient theater and, now happy, she finds the answer: these well-structured stone, wide seats that stand proudly over time are the reason for the exquisite acoustics that make two words sound everywhere! At midnight, in her room, gazing at the stars, she wonderingly whispers: "But, how?". Two words in the room, without result. Nevertheless, this is the feeling of echo and Vasiliki's journey that Acts on the Aura = Epidaurus.
