PLOT

Several terrorists penetrate the building of the World Health Organization in Geneva to bomb a laboratory where dangerous bacteriological weapons are being developed. They are discovered and a shoot-out ensues during which several vials containing highly infective viruses are broken. One of the terrorists manages to flee by hiding on the Geneva-Stockholm train, unaware that he has been infected. A manhunt is begun by the American Secret Service which, having verified the man’s presence on the train, order the authorities to seal the train and divert it toward a precarious bridge that is no longer in use, the Cassandra Crossing, in Poland. A well-known doctor on the train, assisted by his wife and other passengers, fearlessly strives to keep things from getting worse. Not without danger, some of the passengers manage to save themselves by dividing the train into two parts, while the others perish in the collapse of the bridge. (Enrico Lancia)
