A dead man hangs from the portal of St. Paul's Chapel in Damascus. He was a Muslim officer and he was murdered. But when Detective Barudi sets out to interrogate the man's mysterious widow, the Secret Service takes the case away from him. Barudi continues to investigate clandestinely and discovers the murderers motive: it is a blood feud between the Mushtak and Shahin clans, reaching back to the beginnings of the 20th century. And, linked to it, a love story that can have no happy ending.
