In 1979, a young couple, Carole and Jérôme, go behind the Iron Curtain to Odessa on a vacation to celebrate their engagement. At least, that’s their story. In truth, they are cousins who have come to the USSR to secretly meet with persecuted Jews denied visas to leave the Soviet Union. By day, Carole and Jérôme act like tourists, but by night, they reach out to the so-called “refuseniks” in an attempt to help them flee the country. As the pair begins to infiltrate this dark, Cold War world, they’re confronted with a reality they never expected. Throughout, Carole is motivated by political commitment and a taste for danger, but it soon becomes clear that Jérôme has a hidden agenda.
