This is a fairy tale set in a modern city. The story's heroine is Wenwen, an inflatable doll who seems to possess a touch of magic. The other main character is Xiaotian, a security guard at a shopping mall. One night, while Xiaotian and his captain, Baolong, were catching the thieves Dabing and Erdan, they accidentally knocked Wenwen over, and one of the thieves' machetes slashed her. Later, while cleaning up the scene, Xiaotian found Wenwen deflated. He patched her wound with clear tape and blew her back up until she stood upright again. Then a miracle happened: Wenwen's head suddenly turned toward him as he walked away, as if watching him go. From then on, Wenwen came to life every night, and the shopping mall became her stage. By a strange coincidence, she kept running into Xiaotian. Dutiful as ever, Xiaotian couldn't ignore any suspicious figure. So during one pursuit, he accidentally injured Wenwen again. Just like last time, he had to patch her up and blow her back up. As Wenwen gradually returned to her lifelike state, Xiaotian began to feel uneasy. He couldn't understand why he was so sensitive about a dummy! After he blew her up a second time, even more miracles followed: Wenwen began to seem more and more like a real person. Looking at her, Xiaotian often thought of the girlfriend he'd already broken up with. And so began a poignant, fantastical encounter...
