Fifty years have passed since the issue of refugees fleeing to European cities in search of safety. The United Nations built five cities dedicated to refugees to gain their right: security. Morozov City near Russia. Cirillo City near Italy. Maltova City is adjacent to Cirillo City. Rose City near France. Tudur City near the UK. Ulriika City in Finland. The refugees managed to build their new life. Now, these five cities are expanding rapidly and have their characteristics. Raymond Cooper—a former police detective at Morozov City, decided to resign from his job and move to Cirillo City to reinvestigate the murder case of his late friend, Arnold Walter after police decided it as a failed robber attempt that led to the murder. With a piece of paper that he found from his friend's hand, he searched for clues that led him to a girl named Amanda Chloe. All the investigations he carried out in the city of Cirillo led him to the trauma and old wounds he had received from his past. Will he be able to deal with it and finish his investigation?
