On the first day of the monsoon an old ramshackle building appears. This is The Rainfall Market. Inside you will find magical bookstores, hairdressers, perfumeries and anything your heart desires. But you cannot enter without an invitation. Serin, who lives in a small flat with her mother and dreams of a bigger, better life, can't believe her luck when she receives a ticket inviting her to step inside The Rainfall Market. Once inside she will have the opportunity to swap her life for a new one. A better one. Accompanied by Isha the cat and followed by a mysterious shadow, Serin tentatively steps inside. There she is told she has just one week to choose the perfect life and find true happiness. However, there is a catch. If she doesn't find her dream life, she'll be trapped inside the market forever.
