A small disparate group of people are aboard a multi-day, multi-stop flight from Mexico City to Buenos Aires. Beyond the crew of pilot, Roberto Beltrán, a loner, his co-pilot Carlos Cervantes who is always looking for love, and Paco the flight steward, the passengers are: spoiled and rich Jorge Mancera and his innocent fiancée Margarita Téllez, who are posing as a businessman and his secretary but who are really running away to elope in Venezuela; elderly Marta Ortos and her henpecked husband, Professor Enrique Ortos, a botanist and anthropologist, the two who probably only have stayed married for as long as they have out of inertia; "Pibe", a young adolescent boy who is traveling with his male nanny, Pedro, ahead of the boy's professional polo playing father who will join them in Buenos Aires on a later flight; Lucy Alcázar, who most of the other passengers believe to be a trollop as a young woman traveling alone; and Sr. Ibáñez, a bounty hunter, who is transporting Sr. Vázquez, a bank robber and murderer, back to Argentina, the country of the crimes, so that Ibáñez can collect his reward and Vázquez face certain execution. On the second leg of the flight, the plane is thrown far off course in a tropical storm, and combined with mechanical difficulties, they are forced to crash land somewhere in the jungle. Those that live through the crash have to band together for their survival, they needing to figure out if the natural order of their civilized lives applies in who will do what, most specifically who will make the important decisions. The plane may be repairable, but as time progresses and they learn of certain hazards in the area, they will have to make some difficult decisions in this matter, and in matters that may affect life or will affect certain death.
