Heldt's colleagues and best mates give the games-lover an original birthday present: they all enter Bochum's original, never-solved escape room aboard a converted airplane "Flug des Todes" (Death Flight). Mario Korthals, Dr. Holle, Grün, Ellen Bannenberg, Heldts and buddy Achmed are costumed as pilot, stewardess, air-marshal, first- and tourist class passengers, joined by two outsider: engineer John Kuhl and hairdresser Tatjana Klug who won her ticket by accident. Security-agent Patrick Lessig checks them in, warning to trust or believe nothing, but Achmed soon collapses from claustrophobia, the compartments are locked. After successfully preventing the simulated crash, the team is told s fiend took over control and seeks lethal vengeance. It turns out this threat has layers, only partially part of the game, with a legacy hacker posing the gruesome threat, as forensic deputy Monthomery simultaneously finds out by identifying the knocked-out and replaced escape room executive.
