Nightmare's Passengers is based on a true story that for several months in 1981 was splashed all over Argentina's front pages. The horribly mangled bodies of a prominent married couple are discovered in the trunk of a car. The sons of the victims are interrogated, and in flashback the younger son (Gabriel Lenn) tells "all." The boys' father (Federico Luppi) was a well-connected executive and secret homosexual; the mother (Alicia Bruzzo) was an alcoholic who sought an incestuous relationship with her sons. While the film never answers the question as to who committed the murder (no verdict had been reached at the time of filming) it devotes plenty of screen time to the depraved lifestyle of the victims--and also condemns the military junta then running Argentina, which allowed certain privileged people to behave as aberrantly as they wished so long as they were loyal to the junta. Originally titled Pasajeros de Una Pesadilla, Nightmare's Passengers was based on the book by Pablo Schoklender, the real-life younger son in the actual case.
