It is the late 1960s and General de Gaulle has cancelled Israel's order for fifty Mirage 5 jet fighters - a stunning body blow for the Israeli Air Force, depleted by SAM missiles after the Six-Day war. Now de Gaulle springs another surprise, embargoing the five missile-carrying high-speed craft under construction for the Israeli navy. Against this background, Daniel Kalen, an Israeli fighter pilot grounded after injury, has been given an extraordinary mission by Mossad: to steal the Mirage blueprints - all 250,000 of them - so that Israel can build her own version of the fighter.
