Roger Quain, escorting two zoo-bound black panthers on the train from Milan to Paris, is unaware that a Western agent, Catherine Ullven, has hidden a microfilm in the collar of one of the animals. But when the train is derailed in the Swiss Alps and the panthers escape, she is forced to involve him in her mission, which now includes enemy agents hunting the microfilm, the animals, Catherine and Roger.
