I viaggiatori della sera is a 1979 Italian/Spanish science fiction-drama film written and directed by Ugo Tognazzi.
[1] In an alternative 1980 future, recently approved laws mandate that everybody must retire and move into state-run vacation villages upon reaching their 50th birthday.
Here, although provided with free food, alcohol, entertainment and all perks of a promiscuous life style, the guests are effectively prisoners who get progressively decimated, by winning a "cruise" from which there is no return.
The movie follows the experience of a couple forced into the new reality, under pressure of their own sons and society as a whole.
Their sons are relatively at ease with the new system, which is in turn embraced unquestionably by their own child.
