Based on the novel The Old Axolotl by Polish author Jacek Dukaj, this six-episode series melds a sci-fi premise with a suspenseful dramatic mechanism. Midnight, Brussels. Sylvie (Pauline Etienne) awakens from the dream, late for her flight. With an urn full of her recently deceased lover’s ashes in her backpack, she eventually ends up on her flight to Moscow. Elsewhere in the airport, little dramas unfold. Terenzio (Stefano Cassetti), who claims to be with NATO, very nervously and desperately buys a ticket to anywhere. A first-class jerk (Jan Bijvoet) complains that an elderly man in a wheelchair gets to board before he does. A famous influencer (Alba Gaia Bellugi) says her friend made a choking sound in the middle of a call and hung up, she’s now worried, she says to a concerned onlooker (Mehmet Kurtulus). Terenzio sees an image of dead people on TV, and bolts. He knocks over an armed guard, grabs his machine gun and takes the partly filled Moscow plane hostage. While arresting control of the cockpit, he fires a bullet through the hand of the co-pilot. Now he can’t fly the plane, but thankfully, Sylvie is a former military helicopter pilot, and she steps in to assist. The passengers consist of the first-class jerk, the famous influencer and the concerned onlooker. Terenzio makes Sylvie and Mathieu point the plane towards New York. He explains that the sun is murdering people, and so they have to fly west, away from the sunrise. But the plane has limited fuel reserves, not to mention it lacks the engine capacity too.
