The film is about traveling on a flight from Kansas to Los Angeles. Henry is bringing a hamburger of hamburgers to travel with him on board. For scientific purposes, the pilot tells him, and some passengers say it is forbidden, The pilot asks for the emergency landing, and the passengers are surprised that the authorities have turned the airport into a quarantine place that has no exit and that they have to find a way out. Terror spreads throughout the place.
Lacking a budget and stars, the filmmaker reworks the viral viciousness into a modest but highly entertaining follow-up, dropping tedious found footage elements to refresh the concept.
