Industrialist Fernando Cebrián goes on a vacation with his wife, Geraldine Chaplin, and his best friend, Juan Luis Galiardo. Cebrián thinks the two of them are having an affair.

There's macho posturing and fantasizing aplenty in this early movie by Carlos Saura. Given that he and Miss Chaplin were starting their own longterm affair, it;s an interesting question how much of this is based on his own issues about the relationship, but that makes little difference to the casual or even dedicated movie watcher. The scenes in the desert and later by the seaside are strikingly shot by DP Luis Cuadrado, and the relationships are interestingly realized..... assuming they're realized within the movie or present only as the fantasies of the characters.
