A female thief blackmails her former gang members into one last job of stealing jewels from a bank during the bull running in Pamplona. It is Giovanna Ralli who controls the gang, but it is Stephen Boyd who is the brains behind the actual robbery. Yvette Mimieux is his girl friend and and the source of the godd twist at the end of the film. The background in Pamploma gives some good visuals in an otherwise standard heist plot. The film is somewhat let down by some weak characterisations.
