A "modern western", made in West Germany. Films of this ilk would leave a 1990s cinema audience completely puzzled. It can only be understood in the context of a society where cigarette companies were advertising "den Duft der grossen weiten Welt" (the smell of the whole wide world), when movies had gratuitous helicopter shots (that is: shots OF helicopters) to indicate importance, when damsels in distress were abundant in cinema, preferably in tight sweaters, when European cinema still made films that were supposed to entertain an unsophisticated mass audience, etc.
What am I squirming about? Well, we have here a bunch of Mexican bandits played by well-known German actors - they look as Mexican or banditrious as, say, George C. Scott does. Clearly, the assumption in 1965 was that the intended audience had never seen a Mexican in their lives, or a bandit for that matter - probably a correct assumption. To be precise, this is only one of the minor flaws of the film, in comparison. Our willingness to suspend disbelief is overstretched, the plot about three German women captured by Mexican bandits is frankly ludicrous.
