Angela is a successful writer, widowed and wealthy. Her son Sean was born in London where he attends university, while she lives in a small town in northern Italy. Fatima is Maghreb like her husband but her children Nadia and Tarik were born in Italy: Nadia married an Italian Catholic against the wishes of her Muslim father and Tarik studies in England. The English university is the place where the destinies of Sean and Tarik meet because they both fall under the influence of Omar, a recruiter on behalf of the Jihad. Sean and Tarik, inflamed by the man's words, will enlist to fight in Syria, throwing their respective mothers into despair. Angela and Fatima's paths cross at a psychological support group run by Dr. Diana. The group also includes Israeli Sam, who killed a terrorist before he carried out a massacre, Claire, whose husband and son died in a jihadist air strike, and Eric, whose daughter Sofia joined the freedom fighters, coincidentally as Omar's concubine.
