There’s also a famous Finnish legend about a magical ball ornament that glows when you hold it and sing a phrase to it. The idyllic, seaside town of Rauma holds a secret: There’s a secret universe within the city. Some say it is a connection between two different and distant countries. Luna Lylastien is a native Finn. She works as a part-time detective for Rauma's main crime unit and has the near-to-perfect life in the city. She leads a double life, however, singing with her charming boyfriend, Robin Nieminen. Ryu Jaekwan is an aspiring young Idol-actor in Seoul, South Korea. After a powerful concert with his group, “Legendary,” he lands the lead male role for an up-and-coming 12-episode K-Drama named “Replay,” as Park Sang-beom. He instantly gains chemistry with the seasoned actress, Shin Eun-ji. One day, Eunji and Jaekwan are told that the next dose of filming for “Replay” is taking place in the heart of the mysterious Rauma, Finland. They are instantly swept up into an array of chaos, along with a string of jealousy, bonding and a complex web of romance and thrills as Luna finds a peculiar hockey stick in a pawn shop cellar. Together, Finns and Koreans can either solve the mysteries surrounding Rauma’s secrets, including the peculiar hockey stick and connect the worlds of South Korea and Finland or drive the two countries apart. Or…maybe this is just yet another Urban Legend
