Jake Ord and Magda are recovering from the trouble in the previous adventure when Ord's old boss in British Intelligence asks him to babysit a Russian asset. Ord declines but the little matter of Magda's false passport and activities is mentioned so now Ord and Magda are picking up the asset in Montenegro and taking him temporarily to Portugal until he can be exfiltrated - all the while some very determined and capable people try to kill all three.
