American novelist David Raybourne accidentally becomes entangled in the Red Brigade's terrorist plan to kidnap Italian Premier Aldo Moro during a research trip to Rome. As the terrorists attempt to kill David, he and his photojournalist friend must struggle to stay alive.
In the past few days Rome has been the scene of a singular event: when it rains, the manholes exhale a dense steam whose origin and composition is unknown. No one can imagine that whoever breathes in the mysterious substance will have to deal with what he/she represses, their darkest instincts, their anger. Not even the Morel family.
The librarian of the university Xenia schedules a S&M blind date with the masochist Ghost to satisfy her fantasies and sexual desires. They spend the night in his apartment having kinky sex and on the next morning Ghost is dead with slashed throat. Xenia cleans her evidences and leaves the place, but Ghost's friend Silver investigates the murder of Ghost and finds her files in a CD.
