A French-Canadian part based on real events. In 1944, German scientist Emil discovered how to find a uranium bomb before the US. Working instead of sharing information with the Nazis. Meanwhile, the French ally spy Simone is on duty to find out how much he knows and how to kill him, even though he has a mixed history with Emil, he knows how much. In the meantime, the Nazis know something about Emil and they’re looking for him. Everything comes to your head when they’re on a train.
In summary, this is not really a horror movie. But this is a thriller thriller of human monsters.
