Yun is missing! The search for her sister takes the Chinese woman Mei to Italy, to the Eternal City, to the casino “Città Proibita”. The disreputable establishment is in the hands of Chinese gangsters who show little cooperation in the search for her missing sister. A serious mistake, because Mei has been trained in kung fu by every trick in the book all her life. Ruthlessly, she soon cuts her way through Rome’s underworld – and meets Marcello, a kind-hearted pasta chef who is in debt to a mobster.
