A briefcase with undisclosed contents – sought by Irish terrorists and the Russian mob – makes its way into criminals' hands. An Irish liaison assembles a squad of mercenaries, or 'ronin', and gives them the thorny task of recovering the case.

Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
