The Cassandra Crossing

An alarming discovery is made at the U.S. mission within the International Health Organization regarding a strain of pneumonic plague. This revelation triggers panic and urgency as officials recognize the potential implications of a biological weapon of mass destruction being in play.

A trio of terrorists hatches a nefarious plan to unleash chaos across America by spreading the plague. Although two of the terrorists are taken down by security forces, the remaining conspirator manages to escape and ends up hospitalised, revealing his identity as Swedish.

Dr. Elena Stradner engages in an intense exchange with Colonel Stephen Mackenzie about the plague strain's nature. Stradner worries it is a bioweapon, while Mackenzie insists it is merely intended for disposal, highlighting the urgency of their situation.

The remaining terrorist, Eklund, cleverly evades capture by hiding on a train traveling from Geneva to Stockholm. His escape underscores a looming threat as authorities scramble to contain the situation and intercept the possible biological hazard.

As Dr. Stradner pushes for immediate interception of the train, Colonel Mackenzie proposes an alternative route to an abandoned railway leading to Janov, a former Nazi concentration camp. This decision raises concerns about the safety of the passengers on board.

The train is filled with a diverse group of individuals, including renowned neurologist Jonathan Chamberlain, his ex-wife Jennifer, Holocaust survivor Herman Kaplan, and Nicole Dressler, the wife of a German arms dealer. Their personal stories intersect as they face the growing threat.

Chamberlain learns about a caged basset hound found among the passengers' belongings, inadvertently infected with the plague. This shocking discovery escalates the urgency, prompting drastic measures to contain the potential outbreak.

Mackenzie attempts a helicopter evacuation of Eklund, who poses a significant threat, but the operation fails. This failure adds to the mounting tension as the train nears a tunnel, intensifying their race against time.

Chamberlain grapples with the grim reality that the plague has a mortality rate of 60%. As the crisis deepens, he proposes isolating the infected section of the train, but Mackenzie dismisses the idea, prioritizing orders over the truth.

With the situation spiraling out of control, Chamberlain allies with Haley, the undercover agent, to take control of the train. Their decisive actions reflect a desperate bid to prevent disaster at the unstable Kasundruv Bridge.

In a selfless act, Haley sacrifices her life to protect a young passenger amidst the chaos, showcasing the human cost of the unfolding crisis. Her bravery highlights the dire stakes involved as tensions escalate aboard the train.

Kaplan uncovers a sinister plot to sabotage the train's gas supply and critical coupler. Fueled by a desire for justice, he willingly ignites an explosion, marking a pivotal moment in the struggle for survival.

Following Kaplan's sacrifice, Chamberlain takes decisive action to disconnect the train’s rear segment. This bold move is aimed at lightening the load, enabling the remaining cars to safely cross the precarious bridge.

Tragedy strikes as the Kasundruv Bridge collapses under the strain, resulting in the loss of everyone in the front half of the train. The horrific outcome further amplifies the enormity of the crisis faced by the survivors.

In the somber aftermath, the surviving passengers are evacuated and must confront the reality of their freedom from quarantine. Meanwhile, Stradner carries the weight of hope for survivors in Geneva, as Mackenzie faces scrutiny from his superiors regarding the unfolding biological scandal.
