Beware of the Jönsson Gang

Ten months in prison have done nothing to Sickan (Gösta Ekman) except give him time to think, and the offer waiting for him on release comes from a banker called Wall-Enberg Jr., who will say very little about himself. The job is the Bedford Diamonds, and the place is Switzerland. Jonas Cornell puts Sickan back beside Ragnar Vanheden (Ulf Brunnberg), and their old partnership of bickering and loyalty carries most of the film.
