October 2016: Iraqi forces, backed by the US, are preparing to wrestle Mosul back from ISIL. Mam, the leader of an elite French commando unit, captures a high-ranking jihadi, Zaid, who’s prepared to do a deal. If Mam can get his daughter, Salwa, and his grandson away from her warlord husband and safely out of Mosul, Zaid will hand over vital intelligence to prevent further attacks.
