Israel is placed in an unforeseen situation: one of the rockets which hit Tiberias, and was presumably fired by Palestinian terrorists, had a "nuclear tip." It marked unacceptable escalation
between Isarel and its enemy neighbors. Mossad and Shin Bet are drafted to clarify the challenge, together with Countess Renate's Shadow Experts. Concluding that the nuclear tip of the rocket was radioactive elements sourced from nuclear waste, the Israeli secret services follow different scenarios to identify the guilty party.
The first thread involved led Mossad to Iraq, where they discovered an unknown ISIS camp in Syria. The agency had to destroy the lethal elements of the camp's activities and possibly involve Iran, the suspected backer of this new terrorist unit. The second idea was to trace the origin of the nuclear waste to Paris first and then to the southeast of France. Could this area be for nuclear waste what Marseilles was to the narcotics trade half a century ago?
Or was it the escalation in the rocket launching activities of terrorists toward Israel; the one step too far which would inflame the region?
