  "description": "Letnie kolonie, tłum dzieci, a wśród nich Ania i Mania. Dziewczynki podobne do siebie jak dwie krople wody. Jak to możliwe? Nikt tego nie wie. Na początku nic nie zapowiada przyjaźni, ale szybko okazuje się, że łączy je znacznie więcej, niż myślą. Wówczas wpadają na szalony pomysł. Jeżeli plan się powiedzie, ich życie całkowicie się zmieni, już na zawsze...",
